Evaluation SDKs (software development kits) allow you to try out CartoType before you buy a license. You will be able to create a test application and  find out whether CartoType is the right solution for you. The evaluation SDKs have a few restrictions, including placing a watermark on every map, but provide access to the complete API (application programming interface) and all features including graphics-accelerated rendering.

The CartoType evaluation SDKs (software development kits) are provided for evaluation only, excluding any commercial use. For commercial licensing please contact us.

By clicking on any of the links on this page, or by using the SDK material, however acquired, you accept the terms of the CartoType Evaluation License and you also accept that neither CartoType Ltd, nor any owners, shareholders or officers of CartoType Ltd, or any other contributors to, authors of or maintainers of the CartoType system, are liable for any damage, direct or consequential, caused by downloading, installing or using the SDK, or by any programs built using the SDK, and that the SDK is not warranted fit for any particular use and is for evaluation use only and may not be used for any commercial purpose.

To uninstall any of these SDKs, all you need to do is delete the files from your computer.

Sample Maps

To save download time, the SDKs contain only a single sample map. It is of the Isle of Wight, an island off the southern coast of England, chosen because of its good mix of features: urban, rural, and coastal. You can download more maps if you need them. Please contact us if you need a map of any particular area for evaluation purposes.

Sample Code

The source code for most of our demonstration programs is available in public GitHub repositories in the account https://github.com/CartoType. The name of each repository indicates which release it is intended for. For example, the repository named CartoType-Public-4-4 contains sample code for CartoType version 4.4. The code is supplied under the permissive MIT license.

Release notes

The current version of the CartoType SDK is release 5.0. It was released on 7th February 2018.

The current build is 5.0.100, uploaded on 8th May 2018.

important changes since 5.0

fixed case 2228: vehicle position doesn't take account of offset when graphics acceleration is used

polygon layers with no fill colour but possessing a border color were not drawn in GL
layers disabled before creation of a vector tile server could not be re-enabled
fixes case 2244: envelopes for linear found items are drawn wrongly in GL
added support for importing route relations for walking, cycling and skiing from OSM data
draw scale and legend in Maps App when graphics acceleration is enabled
added ZoomAt and Pan overloads with 'from' and 'to' arguments to the iOS and .NET SDKs
complex (non-rectangular) gabled roofs are now drawn
made graphics acceleration easier to use on Windows
added graphics acceleration to the .NET SDK
fixed case 2253: makemap fails to load TIFF file with non-integer bounds in degrees latitude and longitude
fixed case 2254: images loaded from bitmaps are not drawn by graphics acceleration
added 'int' attribute to the commit command in the import rules language
added /copyright command line option to makemap
fixed case 2235: turn instructions are sometimes incorrect for multiple-lane junctions

fixed regression: facing sides of 3D buildings in non-GL mode were discarded instead of facing-away sides
fixed subscript out of range causing crash in turn-expanded router
string concatenation expressions were not compiled
makemap no longer unnecessarily writes more than 65535 string table entries
changed the way data is invalidated when drawing using graphics acceleration to avoid flashing when rapidly updating dynamic data such as verhicle positions and routes
hospitals, motels and universities are now geocoded as buildings, not land features, which means they now get proper addresses
identical labels are now folded when creating the texture atlas; prevents the texture atlas from filling up when drawing large numbers of pushpins
fixed a crash in Find caused by a missing check for null
the maps app now forces Qt to use a library supporting OpenGL ES; allows it to work on a larger variety of platforms and particularly helps on Windows
the .NET SDK now includes a 32-bit build again

bug fix: graphics acceleration was not enabled in the evaluation SDKs

The Android SDK

The Android SDK allows you to use CartoType with the Android operating system. You use the CartoType Android API, which gives you access to all the features of CartoType: loading maps, adding your own objects to the map, panning, zooming, address searching, routing and navigation.

Download link: Android SDK

The SDK is a ZIP file of about 18Mb. It contains a folder called cartotype_android_sdk_evaluation containing the following folders:

libs: a JAR file with the CartoType Java classes, and the compiled native-code libraries as .so files. The native-code library is supplied in various arm and x86 versions.

font: standard fonts; for simple CartoType use you need load only DejaVuSans.ttf

map: sample maps

style: the standard style sheets; you should load standard.ctstyle with the sample map

doc: licenses and acknowledgments for third-party libraries

You will probably also need to look at some sample Java code using CartoType. This is the source of NavigatorApp, our simple demonstration application available for download from the Google Play Store:

NavigatorApp source code

If you want to compile this code you'll need to add cartotype.jar and libcartotype.so from the Android SDK to your project. The data files - sample map, style sheet and fonts - are already included in the sources, in the 'assets' folder. There is also a very simple testbed for the graphics accelerated version of CartoType for Android:

sample Android code with graphics acceleration


The iOS SDK allows you to build CartoType apps for the iPhone and iPad. It is supplied as a .dmg file (Apple Disk Image) containing the file CartoType.framework. You use the CartoType iOS API, written in Objective C, which gives you access to all functionality.

Note: in order to avoid linker errors when using the -ObjC flag, you need to have at least one ".cpp" (C++) or ".mm" (Objective C++) source file in your own project, even if it's an empty one. If your project has ".m" (Objective C) and ".h" files only you will get linker errors because Xcode won't know that there is both C++ and Objective C code in the project.

Download link: iOS SDK

This is a 167Mb download containing the header files and compiled libraries for the simulator and device targets as a .dmg file. A sample map, style sheets and fonts are also included. The download is large because it is a fat binary, containing versions of the libraries for different platforms and processors, and it is compiled using bitcode, which is now necessary for creating releasable iOS apps.

(If you are upgrading to a new version of the CartoType iOS SDK, you may sometimes find that Xcode does not recognize new Objective C headers or classes. You can usually fix this problem by closing your project, opening the organizer from the Xcode Window menu, select your project, then click on 'delete' opposite 'derived data'. Then close Xcode, reopen your project, clean it and rebuild. Thanks to TigerCoding for this tip from StackOverflow.)

You will also probably want to download the source code and project files for a demonstration program showing the use of the SDK:

CartoType iOS project

Please see CartoType and iOS for instructions on how to build and run this project. There is also a very simple testbed for the graphics accelerated version of CartoType for iOS:

sample iOS code with graphics acceleration

To use CartoType for iOS, you'll need to add the GLKit and OpenGLES frameworks to your project.


This SDK allows you to use CartoType with the .NET framework. You can use any .NET language, such as C#, VB.NET or C++/CLI. You can build a complete application using CartoType in just a few lines of code, as shown in the C# demo program included with the SDK. The .NET SDK (documented here) gives you access to all CartoType features, including map, style sheet and font loading, route calculation, navigation and address searching. It also gives access to graphics acceleration using OpenGL ES 2.0.

Download link: .NET SDK

This is a 30Mb zipped file containing a .NET DLL built for the Intel x64 platform and a C# demonstration program that uses the CartoType DLL, with its source code and data files. An XML documentation file is also supplied. As long as it is kept in the same place as the DLL it will provide tool-tip help for some of the functions.

Note: if you have trouble adding the DLL to your project, in particular if you get a message starting "could not load file or assembly ... CartoTypeWrapper.DLL", please try the following fixes: (i) right-click on CartoTypeWrapper.dll in Windows Explorer and click on 'Properties' in the context menu, then, if you see the text 'This file came from another computer and might be blocked to help protect this computer', click 'Unblock' to the right of that text; (ii) if that doesn't work try installing, or re-installing, the Visual C++ Redistributable for Visual Studio 2015 (please google that phrase to find the current download link).

You should use the 64-bit version of the DLL if possible (that is, if you are running 64-bit Windows), mainly because it allows CartoType to use more heap memory and thus use the fast A* routing system on large maps.

The zip file creates a single directory called CartoTypeDemo when unzipped.

Useful locations

The CartoType .NET DLL

  • x64 release: CartoTypeDemo\vs2017\bin\x64\Release\CartoTypeWrapper.dll
  • x64 debug: CartoTypeDemo\vs2017\bin\x64\Debug\CartoTypeWrapper.dll
  • x86 release: CartoTypeDemo\vs2017\bin\x86\Release\CartoTypeWrapper.dll

Solution files:

  • x64: CartoTypeDemo\vs2017\CartoTypeDemo.sln
  • x86: CartoTypeDemo\vs2017\CartoTypeDemo_x86.sln

Data files

  • sample map: map\isle_of_wight.ctm1
  • standard style sheet: style\standard.ctstyle
  • standard font: font\DejaVuSans.ttf

The DLLs used for graphics acceleration, libEGL.dll and libGLESvs.dll, are in the same locations as the .NET DLLs. They need to be accessible to any application using the CartoType .NET SDK.

Another style sheet and extra fonts are also to be found in the style and font folders. It's always a good idea to load DroidSansFallback as well as any other fonts, because it provides characters for many non-Latin scripts.

The CartoType .NET DLL will not run on non-Intel platforms because the CartoType library is compiled into native code from C++.

The Windows SDK

This SDK (documented here) supports CartoType development for desktop versions of Windows from Windows XP through Windows 8.

Download link: Windows SDK

This is a 66Mb zipped file containing the CartoType header files and debug and release mode libraries for desktop Windows, built using Microsoft Visual Studio 2015 for both the Win32 and x64 platforms.

The zip file creates a single directory called CartoType when unzipped.

The Linux SDK

The C++ SDK (documented here) supports development for Linux (Ubuntu and other x11 versions) on 64-bit Intel platforms. It is a 43Mb zip file.

Download link: Linux SDK

This is a 16Mb zip file containing a folder called cartotype-ubuntu-sdk, which contains the following folders:

bin: the release-mode evaluation CartoType library, and the makemap tool for creating maps

font: standard fonts; for simple CartoType use you need load only DejaVuSans.ttf

header: the C++ header files; you need to include only one of the header files, cartotype_framework.h, to use CartoType

map: a sample map

style: the standard style sheets; you should load standard.ctstyle with the sample map

Linux SDK notes

  • The CartoType Linux library is built for 64-bit Intel platforms.
  • You may need to add the option -pthread to both compiler and linker options, otherwise you might get a linker error for pthread_create.
  • Don't define the preprocessor macro _DEBUG in the debug build or you will get link errors in that build (because CartoType::TResult changes from a plain integer to a class).
  • Set the compiler option +std=c++14, because CartoType uses C++14.
  • If you get linker errors mentioning types in the std namespace, the cause is probably that the CartoType Linux Library is compiled using GCC 5.1, and you are using GCC 4.9 or earlier.
