VTS Browser JS

VTS Mapproxy is a 3D geospatial data streaming server.

VTS Mapproxy provides on-the-fly access to an array of raster and data vector formats and serves those data in formats optimized for 3D streaming and rendering.

Features

  • dynamic TIN (terrain meshes) generation from DEMs (digital elevaton models)
  • on-the-fly CRS conversion for massive raster datasets
  • vts-geospatial remote tileset provider
  • CesiumJS terrain provisioning
  • WMTS service for raster datasets
  • introspection capabilities (web-based, interactive resource directories with embedded viewers)

User documentation

VTS-Mapproxy user documentation is available at the vts-geospatial website.

Authoritative resource-definition documentation is available in separated document.

Download, build and install

You basically need just 2 steps to get VTS-Mapproxy installed: git clone the source code from the repository and make it. But there are some tricky parts of the process, so read carefully following compilation howto.

Dependencies

Basic deps

Make sure, you have cmake and g++ installed, before you try to compile anything.

sudo apt-get update
sudo apt-get install cmake g++

VTS dependencies

Before you can run VTS-Mapproxy, you need at least VTS-Registry downloaded and installed in your system. Please refer to related README.md file, about how to install and compile VTS-Registry.

Unpackaged deps

VTS-Mapproxy is using (among other libraries) OpenMesh. You have to download and install OpenMesh library and this is, how you do it

git clone https://www.graphics.rwth-aachen.de:9000/OpenMesh/OpenMesh.git
cd OpenMesh
mkdir build
cd build
cmake ..
make -j4
sudo make install

Installing packaged dependencies

Now we can download and install rest of the dependencies, which are needed to get VTS-Mapproxy compiled:

sudo apt-get install \
    libboost-dev \
    libboost-thread-dev \
    libboost-program-options-dev \
    libboost-filesystem-dev \
    libboost-regex-dev \
    libboost-iostreams-dev\
    libboost-python-dev \
    libopencv-dev libopencv-core-dev libopencv-highgui-dev \
    libopencv-photo-dev libopencv-imgproc-dev libeigen3-dev libgdal-dev \
    libproj-dev libgeographic-dev libjsoncpp-dev \
    libprotobuf-dev protobuf-compiler libprocps-dev libmagic-dev \
    libtinyxml2-dev libmarkdown2-dev \
    gawk sqlite3

Clone and Download

The source code can be downloaded from GitHub repository, but since there are external dependences, you have to use --recursive switch while cloning the repo.

git clone --recursive https://github.com/melowntech/vts-mapproxy.git

NOTE: If you did clone from GitHub previously without the --recursive parameter, you should probably delete the vts-mapproxy directory and clone again. The build will not work otherwise.

Configure and build

For building VTS-Mapproxy, you just have to use make

cd vts-mapproxy/mapproxy
make -j4 # to compile in 4 threads

Default target location (for later make install) is /usr/local/ directory. You can set the CMAKE_INSTALL_PREFIX variable, to change it:

make set-variable VARIABLE=CMAKE_INSTALL_PREFIX=/install/prefix

You should see compilation progress. Depends, how many threads you allowed for the compilation (the -jNUMBER parameter) it might take couple of minutes to an hour of compilation time.

The binaries are then stored in bin directory. Development libraries are stored in lib directory.

Installing

You should be able to call make install, which will install to either defaul location /usr/local/ or to directory defined previously by the CMAKE_INSTALL_PREFIX variable (see previous part).

When you specify the DESTDIR variable, resulting files will be saved in $DESTDIR/$CMAKE_INSTALL_PREFIX directory (this is useful for packaging), e.g.

make install DESTDIR=/home/user/tmp/

Install from Melowntech's package repository

We provide precompiled packages for some popular linux distributions. See Melowntech's OSS package repository for more information. This repository contains all needed packages to run VTS OSS software.

Run VTS-Mapproxy server

First you need to create mapproxy.conf configuration file. You then can run

mapproxy --help
mapproxy --config mapproxy.conf

NOTE: You might need to add also --registry parameter, and point it to previously compiled VTS-Registry.

Description of the configuration file can be found in our user documentation.

The server is not intended to be exposed to the Internet as it is, instead it's advised to hide it behind e.g. NGINX server.
