The release of QGIS 2.6 is planned for October 24, but you don’t have to wait to test new functions in development. In this post I’ll look closer on two new features that in my mind will make GIS life easier, even if some improvements should be made with the first of the new features described here.
A short time ago I’ve posted an article on the installation of QGIS in combination with a PostGIS database in the background. As we all know, Windows is mostly used as OS on a PC so this is the Windowized version. This is a short summary that sums up the article of a site called Boston GIS. I’ll show you how to install QGIS version 1.8 (which will be updated in some days) and PostgreSQL with PostGIS extension and show you the first steps in the import of shapefiles and raster data.
A lot of you out there are probably working on Windows Systems using ArcGIS and I have to admit that the possibilities with ArcINFO in the background and a proper GDB (GeoDataBase) are really big. But let’s be honest: A lot of your tasks are more or less everyday business, right?! So let us have a look on building a GIS workplace using QGIS 1.8 (which will be updated the big way in some days/weeks) and PostGIS which is a spatial enhancement of PostgreSQL.
In our last session we started with some topographic “pre”-map as we prepared everything to create a printable map with QGIS which shows heights in a special area. As the map creation itself is somehow very detailed I’ll show you just basic steps so can go into detail with typo and positioning for yourself.
In this tutorial I would like to show you, how to create a topographic map and analyse topographical data using freely available SRTM data and QGIS including some data manipulation. This is part one explaining how to get data, remove missing values, explore the relief and changing the color representation of a TIF file obtained by the USGS.
When I was starting with Ubuntu I was struggling with getting QGIS to run on Ubuntu. Actually it is not a big deal despite of adding a repository to your system. So in this video I am starting with a clean install of Ubuntu 12.04 Precise Pangolin so everyone can follow me: the lines to edit in your sources.list file are:
