pgRouting is an extension of PostGIS (geospatial database), which in turn, is an extension of PostgreSQL database system. It adds routing capabilities and network analysis functionalities to the PostGIS geospatial database. You can perform different network analysis, shortest paths, driving distances, service areas on a topological corrected network. To be able to perform route analysis [...]
For this exercise please use QGIS version 2.18. Various vector layers and tables (OGR, SpatiaLite, PostGIS, MSSQL Spatial or Oracle Spatial) can be edited in QGIS. Before you start a editing session in QGIS, make sure you set the right snapping options (Snapping Tolerance and Search Radius). In QGIS you can find these options in [...]
The CORINE Land Cover (CLC) data consists of an inventory of land cover in 44 classes. Its minimum mapping unit is 25 hectares (in the case of polygon features) and 100 m for lineal features. Datasets are available for the years 1990, 2000, 2006 and 2012, covering the European continent (except Belarus, Ukraine and Russia) [...]
In this exercise we will try to incorporate the height of the build-up areas (average height of 15 m) above the surface of a digital terrain model. In order to do that we will have to follow a few simple steps. Step 1: Load your necessary data into QGIS map canvas Step 2: We will have to [...]
In this exercise we will see how to delineate the boundary of a catchment/contributing area using a Digital Elevation Model and a given point (a specific point for which we want to find the contributing/catchment area). ArcGIS can obtain the total area of flowing into this specific point, also called pour point. In order to [...]
The view matters. Visibility analysis are important from the planning point of view. Visual analysis tools allow you to generate visibility studies over an area, creating an output raster that display what entities can be seen over a certain landscape, from the point of view of one or more observatory. They are used mainly for the planning [...]
A coordinate system is responsible for displaying your data in the right location. Understanding how to properly work with Coordinate Systems can save unnecessary work and reduce the errors you may encounter in the development of the project. Lets see a simple example regarding this matter. We have two layers that represent the country limit [...]
