+<span id="cmake"></span><h1>Using PROJ in CMake projects<a class="headerlink" href="#using-proj-in-cmake-projects" title="Permalink to this headline">¶</a></h1>
+<p>The recommended way to use the PROJ library in a CMake project is to
+link to the imported library target <code class="docutils literal notranslate"><span class="pre">PROJ::proj</span></code> provided by
+the CMake configuration which comes with the library. Typical usage is:</p>
+<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>find_package(PROJ CONFIG REQUIRED)
+
+target_link_libraries(MyApp PRIVATE PROJ::proj)
+</pre></div>
+</div>
+<p>By adding the imported library target <code class="docutils literal notranslate"><span class="pre">PROJ::proj</span></code> to the
+target link libraries, CMake will also pass the include directories to
+the compiler.</p>
+<p>The CMake command <code class="docutils literal notranslate"><span class="pre">find_package</span></code> will look for the configuration in a
+number of places. The lookup can be adjusted for all packages by setting
+the cache variable or environment variable <code class="docutils literal notranslate"><span class="pre">CMAKE_PREFIX_PATH</span></code>. In
+particular, CMake will consult (and set) the cache variable
+<code class="docutils literal notranslate"><span class="pre">PROJ_DIR</span></code>.</p>
+<p>The old CMake name for the PROJ project was “PROJ4” and the switch to
+the name “PROJ” was made with version 7.0. So if you expect your
+package to work with pre-7.0 versions of PROJ, you will need to use</p>
+<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>find_package(PROJ4)
+target_link_libraries(MyApp PRIVATE ${PROJ4_LIBRARIES})
+include_directories(${PROJ4_INCLUDE_DIRS})
+</pre></div>
+</div>
+<p>This will also find version 7.0. This use of the PROJ4 name will be
+phased out at some point.</p>

+<p>PROJ maintains an internal error state, which is local to a
+<a class="reference internal" href="reference/datatypes.html#c.PJ_CONTEXT" title="PJ_CONTEXT"><code class="xref c c-type docutils literal notranslate"><span class="pre">PJ_CONTEXT</span></code></a> thread context.</p>
+<p>See <a class="reference internal" href="quickstart.html"><span class="doc">Quick start</span></a> for more information about how to create and use a thread
+context object.</p>
+<p>If you receive an abnormal return from a PROJ API function (e.g. a NULL
+pointer) you may wish to discover more information about the error.</p>
+<p>In this case you can make a call to <a class="reference internal" href="reference/functions.html#c.proj_context_errno" title="proj_context_errno"><code class="xref c c-func docutils literal notranslate"><span class="pre">proj_context_errno()</span></code></a>, passing in
+your thread context. This will return an integer error code.</p>
+<p>If the error code is zero, the last PROJ operation was deemed successful and no
+error has been detected.</p>
+<p>If the error code is non-zero, an error has been detected. You can pass your
+thread context together with this error code to
+<a class="reference internal" href="reference/functions.html#c.proj_context_errno_string" title="proj_context_errno_string"><code class="xref c c-func docutils literal notranslate"><span class="pre">proj_context_errno_string()</span></code></a> to retrieve a string describing the error
+condition.</p>

+<h1>Version 4 to 5 API Migration<a class="headerlink" href="#version-4-to-5-api-migration" title="Permalink to this headline">¶</a></h1>
+<p>This is a transition guide for developers wanting to migrate their code to use
+PROJ version 5.</p>
+<section id="background">
+<h2>Background<a class="headerlink" href="#background" title="Permalink to this headline">¶</a></h2>
+<p>Before we go on, a bit of background is needed. The new API takes a different
+view of the world than the old because it is needed in order to obtain high
+accuracy transformations. The old API is constructed in such a way that any transformation
+between two coordinate reference systems <em>must</em> pass through the ill-defined
+WGS84 reference frame, using it as a hub. The new API does away with this limitation to
+transformations in PROJ. It is still possible to do that type of transformations
+but in many cases there will be a better alternative.</p>
+<p>The world view represented by the old API is always sufficient if all you care about is
+meter level accuracy - and in many cases it will provide much higher accuracy
+than that. But the view that “WGS84 is the <em>true</em> foundation of the world, and
+everything else can be transformed natively to and from WGS84” is inherently flawed.</p>
+<p>First and foremost because any time WGS84 is mentioned, you should ask yourself
+“Which of the six WGS84 realizations are we talking about here?”.</p>
+<p>Second, because for many (especially legacy) systems, it may not be straightforward
+to transform to WGS84 (or actually ITRF-something, ETRS-something or NAD-something
+which appear to be the practical meaning of the term WGS84 in everyday PROJ related
+work), while centimeter-level accurate transformations may exist between pairs of
+older systems.</p>
+<p>The concept of a hub reference frame (“datum”) is not inherently bad, but in many
+cases you need to handle and select that datum with more care than the old API allows.
+The primary aim of the new API is to allow just that. And to do that, you must realize
+that the world is inherently 4 dimensional. You may in many cases assume one or more of
+the coordinates to be constant, but basically, to obtain geodetic accuracy transformations,
+you need to work in 4 dimensions.</p>
+<p>Now, having described the background for introducing the new API, let’s try to show
+how to use it. First note that in order to go from system A to system B, the old API
+starts by doing an <strong>inverse</strong> transformation from system A to WGS84, then does a
+<strong>forward</strong> transformation from WGS84 to system B.</p>
+<p>With <strong class="program">cs2cs</strong> being the command line interface to the old API, and
+<strong class="program">cct</strong> being the same for the new, this example of doing the same
+thing in both world views will should give an idea of the differences:</p>
+<div class="highlight-none notranslate"><div class="highlight"><pre><span></span>$ echo 300000 6100000 | cs2cs +proj=utm +zone=33 +ellps=GRS80 +to +proj=utm +zone=32 +ellps=GRS80
+683687.87 6099299.66 0.00
+
+
+$ echo 300000 6100000 0 0 | cct +proj=pipeline +step +inv +proj=utm +zone=33 +ellps=GRS80 +step +proj=utm +zone=32 +ellps=GRS80
+683687.8667 6099299.6624 0.0000 0.0000
+</pre></div>
+</div>
+<p>Lookout for the <code class="docutils literal notranslate"><span class="pre">+inv</span></code> in the first <code class="docutils literal notranslate"><span class="pre">+step</span></code>, indicating an inverse transform.</p>

+<p>Looking at the two different programs, there’s a few immediate
+differences that catches the eye. First off, the included header file describing
+the API has changed from <code class="docutils literal notranslate"><span class="pre">proj_api.h</span></code> to simply <code class="docutils literal notranslate"><span class="pre">proj.h</span></code>. All functions in <code class="docutils literal notranslate"><span class="pre">proj.h</span></code>
+belongs to the <code class="docutils literal notranslate"><span class="pre">proj_</span></code> namespace.</p>
+<p>With the new API also comes new datatypes. E.g. the transformation object <code class="docutils literal notranslate"><span class="pre">projPJ</span></code>
+which has been changed to a pointer of type <code class="docutils literal notranslate"><span class="pre">PJ</span></code>. This is done to highlight the
+actual nature of the object, instead of hiding it away behind a typedef. New data
+types for handling coordinates have also been introduced. In the above example we
+use the <code class="docutils literal notranslate"><span class="pre">PJ_COORD</span></code>, which is a union of various types. The benefit of this is that
+it is possible to use the various structs in the union to communicate what state
+the data is in at different points in the program. For instance as in the above
+example where the coordinate is read from STDIN as a geodetic coordinate,
+communicated to the reader of the code by using the <code class="docutils literal notranslate"><span class="pre">c.lp</span></code> struct.
+After it has been projected we print it to STDOUT by accessing the individual
+elements in <code class="docutils literal notranslate"><span class="pre">c.xy</span></code> to illustrate that the coordinate is now in projected space.
+Data types are prefixed with <cite>PJ_</cite>.</p>
+<p>The final, and perhaps biggest, change is that the fundamental concept of
+transformations in PROJ are now handled in a single transformation object (<code class="docutils literal notranslate"><span class="pre">PJ</span></code>)
+and not by stating the source and destination systems as previously. It is of
+course still possible to do just that, but the transformation object now
+captures the whole transformation from source to destination in one. In the
+example with the old API the source system is described as
+<code class="docutils literal notranslate"><span class="pre">+proj=latlon</span> <span class="pre">+ellps=clrk66</span></code> and the destination system is described as
+<code class="docutils literal notranslate"><span class="pre">+proj=merc</span> <span class="pre">+ellps=clrk66</span> <span class="pre">+lat_ts=33</span></code>. Since the Mercator projection accepts
+geodetic coordinates as its input, the description of the source in this case
+is superfluous. We use that to our advantage in the new API and simply state
+the destination. This is simple at a glance, but is actually a big conceptual
+change. We are now focused on the path between two systems instead of what the
+source and destination systems are.</p>

+<p>This is a short introduction to the PROJ API. In the following section we
+create a simple program that transforms a geodetic coordinate to UTM and back
+again. The program is explained a few lines at a time. The complete program can
+be seen at the end of the section.</p>
+<p>See the following sections for more in-depth descriptions of different parts of
+the PROJ API or consult the <a class="reference internal" href="reference/index.html"><span class="doc">API reference</span></a> for specifics.</p>
+<p>Before the PROJ API can be used it is necessary to include the <code class="file docutils literal notranslate"><span class="pre">proj.h</span></code> header
+file. Here <code class="file docutils literal notranslate"><span class="pre">stdio.h</span></code> is also included so we can print some text to the screen:</p>

+<p>Let’s declare a few variables that’ll be used later in the program. Each variable

+<p>It is recommended to create one threading context per thread used by the

+<p class="admonition-title">Warning</p>
+<p>The use of PROJ strings to describe a CRS is not recommended. One of the
+main weaknesses of PROJ strings is their inability to describe a geodetic
+datum, other than the few ones hardcoded in the <code class="docutils literal notranslate"><span class="pre">+datum</span></code> parameter.</p>
+</div>
+<p><a class="reference internal" href="reference/functions.html#c.proj_create_crs_to_crs" title="proj_create_crs_to_crs"><code class="xref c c-func docutils literal notranslate"><span class="pre">proj_create_crs_to_crs()</span></code></a> will return a pointer to a <a class="reference internal" href="reference/datatypes.html#c.PJ" title="PJ"><code class="xref c c-type docutils literal notranslate"><span class="pre">PJ</span></code></a>
+object, or a null pointer in the case of an error. The details of the error
+can be retrieved using <a class="reference internal" href="reference/functions.html#c.proj_context_errno" title="proj_context_errno"><code class="xref c c-func docutils literal notranslate"><span class="pre">proj_context_errno()</span></code></a>. See <a class="reference internal" href="errorhandling.html"><span class="doc">Error handling</span></a>
+for further details.</p>
+<p>Now that we have a normalized transformation object in <code class="docutils literal notranslate"><span class="pre">P</span></code>, we can use it
+with <a class="reference internal" href="reference/functions.html#c.proj_trans" title="proj_trans"><code class="xref c c-func docutils literal notranslate"><span class="pre">proj_trans()</span></code></a> to transform coordinates from the source CRS to the
+target CRS, but first we will discuss the interpretation of coordinates.</p>
+<p>By default, a <a class="reference internal" href="reference/datatypes.html#c.PJ" title="PJ"><code class="xref c c-type docutils literal notranslate"><span class="pre">PJ</span></code></a> transformation object accepts coordinates expressed
+in the units and axis order of the source CRS, and returns transformed
+coordinates in the units and axis order of the target CRS.</p>
+<p>For most geographic CRS, the units will be in degrees. In rare cases, such as
+EPSG:4807 / NTF (Paris), this can be grads. For geographic CRS defined by the
+EPSG authority, the order of coordinates is latitude first, longitude second.
+When using a PROJ string, the order is the reverse; longitude first, latitude
+second.</p>
+<p>For projected CRS, the units may vary (metre, us-foot, etc.). For projected CRS
+defined by the EPSG authority, and with EAST / NORTH directions, the order
+might be easting first, northing second, or the reverse. When using a PROJ
+string, the order will be easting first, northing second, except if the
+<code class="docutils literal notranslate"><span class="pre">+axis</span></code> parameter modifies it.</p>
+<p>If you prefer to work with a uniform axis order, regardless of the axis orders
+mandated by the source and target CRS, you can use the
+<a class="reference internal" href="reference/functions.html#c.proj_normalize_for_visualization" title="proj_normalize_for_visualization"><code class="xref c c-func docutils literal notranslate"><span class="pre">proj_normalize_for_visualization()</span></code></a> function.</p>

+existing <a class="reference internal" href="reference/datatypes.html#c.PJ" title="PJ"><code class="xref c c-type docutils literal notranslate"><span class="pre">PJ</span></code></a> object, and generates from it a new <a class="reference internal" href="reference/datatypes.html#c.PJ" title="PJ"><code class="xref c c-type docutils literal notranslate"><span class="pre">PJ</span></code></a> that
+accepts as input and returns as output coordinates using the traditional GIS
+order. That is, longitude followed by latitude, optionally followed by
+elevation and time for geographic CRS, and easting followed by northing for
+most projected CRS.</p>

+<p>A coordinate reference system with an associated transformation to a target/hub <a class="reference internal" href="#classosgeo_1_1proj_1_1crs_1_1CRS"><span class="std std-ref">CRS</span></a>. </p>
+<p>The definition of a <a class="reference internal" href="#classosgeo_1_1proj_1_1crs_1_1CRS"><span class="std std-ref">CRS</span></a> is not dependent upon any relationship to an independent <a class="reference internal" href="#classosgeo_1_1proj_1_1crs_1_1CRS"><span class="std std-ref">CRS</span></a>. However in an implementation that merges datasets referenced to differing CRSs, it is sometimes useful to associate the definition of the transformation that has been used with the <a class="reference internal" href="#classosgeo_1_1proj_1_1crs_1_1CRS"><span class="std std-ref">CRS</span></a> definition. This facilitates the interrelationship of <a class="reference internal" href="#classosgeo_1_1proj_1_1crs_1_1CRS"><span class="std std-ref">CRS</span></a> by concatenating transformations via a common or hub <a class="reference internal" href="#classosgeo_1_1proj_1_1crs_1_1CRS"><span class="std std-ref">CRS</span></a>. This is sometimes referred to as “early-binding”. <a class="reference internal" href="cpp_general.html#general_doc_1WKT2"><span class="std std-ref">WKT2 standard</span></a> permits the association of an abridged coordinate transformation description with a coordinate reference system description in a single text string. In a <a class="reference internal" href="#classosgeo_1_1proj_1_1crs_1_1BoundCRS"><span class="std std-ref">BoundCRS</span></a>, the abridged coordinate transformation is applied to the source <a class="reference internal" href="#classosgeo_1_1proj_1_1crs_1_1CRS"><span class="std std-ref">CRS</span></a> with the target <a class="reference internal" href="#classosgeo_1_1proj_1_1crs_1_1CRS"><span class="std std-ref">CRS</span></a> being the common or hub system.</p>
+<p>Coordinates referring to a <a class="reference internal" href="#classosgeo_1_1proj_1_1crs_1_1BoundCRS"><span class="std std-ref">BoundCRS</span></a> are expressed into its source/base <a class="reference internal" href="#classosgeo_1_1proj_1_1crs_1_1CRS"><span class="std std-ref">CRS</span></a>.</p>
+<p>This abstraction can for example model the concept of TOWGS84 datum shift present in <a class="reference internal" href="cpp_general.html#general_doc_1WKT1"><span class="std std-ref">WKT1 specification</span></a>.</p>

+<p>A CS is the non-repeating sequence of coordinate system axes that spans a given coordinate space. A CS is derived from a set of mathematical rules for specifying how coordinates in a given space are to be assigned to points. The coordinate values in a coordinate tuple shall be recorded in the order in which the coordinate system axes associations are recorded.</p>

+<p>The direction of this coordinate system axis (or in the case of Cartesian projected coordinates, the direction of this coordinate system axis locally) Examples: north or south, east or west, up or down. Within any set of coordinate system axes, only one of each pair of terms can be used. For Earth-fixed CRSs, this direction is often approximate and intended to provide a human interpretable meaning to the axis. When a geodetic reference frame is used, the precise directions of the axes may therefore vary slightly from this approximate direction.

+<p>Abstract class of the relationship of a coordinate system to an object, thus creating a coordinate reference system. </p>
+<p>For geodetic and vertical coordinate reference systems, it relates a coordinate system to the Earth (or the celestial body considered). With other types of coordinate reference systems, the datum may relate the coordinate system to another physical or virtual object. A datum uses a parameter or set of parameters that determine the location of the origin of the coordinate reference system. Each datum subtype can be associated with only specific types of coordinate reference systems.</p>

+<p>Abstract class for a mathematical operation on coordinates. </p>
+<p>A mathematical operation: <ul class="simple">
+<li><p>on coordinates that transforms or converts them from one coordinate reference system to another coordinate reference system </p></li>
+<li><p>or that describes the change of coordinate values within one coordinate reference system due to the motion of the point between one coordinate epoch and another coordinate epoch. </p></li>
+</ul>
+
+Many but not all coordinate operations (from CRS A to CRS B) also uniquely define the inverse coordinate operation (from CRS B to CRS A). In some cases, the coordinate operation method algorithm for the inverse coordinate operation is the same as for the forward algorithm, but the signs of some coordinate operation parameter values have to be reversed. In other cases, different algorithms are required for the forward and inverse coordinate operations, but the same coordinate operation parameter values are used. If (some) entirely different parameter values are needed, a different coordinate operation shall be defined.</p>

Also, the stochastic nature of the parameters may result in multiple (different) versions of the same coordinate transformations between the same source and target CRSs. Any single coordinate operation in which the input and output coordinates are referenced to different datums (reference frames) will be a coordinate transformation.</p>

+code to a class can bit tested with a binary and test. The error class itself
+can be used as an error value in some rare cases where the error does not
+fit into a more precise error value.</p>
+<p>Those error codes are still quite generic for a number of them. Details on the
+actual errors will be typically logged with the PJ_LOG_ERROR level.</p>

+<dd><p>Reduce some mental impedance in the canonical reset/restore use case:
+Basically, <a class="reference internal" href="#c.proj_errno_restore" title="proj_errno_restore"><code class="xref c c-func docutils literal notranslate"><span class="pre">proj_errno_restore()</span></code></a> is a synonym for
+<a class="reference internal" href="#c.proj_errno_set" title="proj_errno_set"><code class="xref c c-func docutils literal notranslate"><span class="pre">proj_errno_set()</span></code></a>, but the use cases are very different:
+<em>set</em> indicate an error to higher level user code, <em>restore</em> passes previously
+set error indicators in case of no errors at this level.</p>
+<p>Hence, although the inner working is identical, we provide both options,
+to avoid some rather confusing real world code.</p>
