Installing TileServer GL on Kali Linux
This tutorial will guide you through the process of installing and configuring TileServer GL on Kali Linux. TileServer GL is an open-source tool that enables you to create vector and raster maps from your geospatial data.
Prerequisites
Before we begin, ensure that you have the following resources available:
- Kali Linux (latest version)
- Node.js (version 12.x or later)
- PostgreSQL (version 10 or later)
- PostGIS (version 2.x or later)
- GDAL (version 2.x or later)
Let's get started.
Step 1: Install Required Dependencies
The first step is to install the required dependencies for TileServer GL. You can do this by running the following commands in your terminal:
sudo apt-get update
sudo apt-get install postgresql postgresql-contrib postgis gdal-bin nodejs npm -y
Step 2: Install TileServer GL
Once all the dependencies are installed, you can install TileServer GL by running the following command:
sudo npm install -g tileserver-gl
Step 3: Configure PostgreSQL/PostGIS
Next, we need to configure our PostgreSQL database to work with PostGIS. To create a new user, a database, and enable PostGIS, follow the steps below:
- Log in to your PostgreSQL database as the default "postgres" user by running the following command:
sudo -u postgres psql
- Create a new user by executing the command below:
CREATE USER tileserver WITH PASSWORD 'password';
- Create a new database for TileServer GL by running the following query:
CREATE DATABASE tiles OWNER tileserver;
- Enable PostGIS extension by running the following command:
CREATE EXTENSION postgis;
To verify that PostGIS is working, you can execute the following command:
SELECT PostGIS_version();
If there were no errors, and the command returned a version number, then PostGIS is installed correctly.
Step 4: Importing Data
In this step, we will import our geospatial data into the database. To do this, you can use the GDAL tools. Let's assume that we have a shapefile called myshapefile.shp.
- Create a SQL file with the necessary configuration by running the following command:
ogr2ogr --config PGCLIENTENCODING UTF8 -f PostgreSQL -lco GEOMETRY_NAME=geom -lco FID=gid -nlt PROMOTE_TO_MULTI -nln mytable PG:'dbname=tiles host=localhost user=tileserver password=password' myshapefile.shp
Note that the -nln mytable parameter is used to specify the name of the table that will hold the data from the shapefile.
- Import the data into your PostgreSQL database by running the following command:
psql -U tileserver -d tiles -f mytable.sql
Step 5: Start TileServer GL
After completing the above steps, you can start TileServer GL by running the following command:
tileserver-gl --config config.json
In the above command, config.json is the path to the configuration file for TileServer GL.
Step 6: Accessing the Map Tiles
Once TileServer GL is up and running, you can access the map tiles by opening a web browser and navigating to the following URL:
http://localhost:8080/data/mytable/{z}/{x}/{y}.pbf
In the above URL, replace mytable with the name of your table, and {z}, {x}, and {y} with the appropriate zoom level, x-coordinate, and y-coordinate for the desired tile.
Congratulations, you have successfully installed and configured TileServer GL on Kali Linux. You can now serve vector and raster tiles using your own geospatial data.
