QGIS is under steady development and with the new release QGIS 2.12 we get some interesting and also visible changes in QGIS. What are the best improvements? Check them out here and decide whether to update or not.
The free and open source gis QGIS started an user survey on its online webpage. The project needs your input to get the best necessary community information for prioritising future adjustments and developments.
Hi guys. Once again I found an interesting question in our Geoscientists group on facebook. One user wanted to show her photos in QGIS as she is it used from Google Maps: See a point, click on it and see the great image you’ve taken on your journey. Unfortunately the most obvious plugins failed to do it in QGIS. So check out our “at least” two usage scenarios for QGIS and ArcGIS where we will handle geotagged photos…Four months ago QGIS 2.8 was released. The Long Term Release will be suppported for the next 2 years. Besides this LTR version QGIS is updated in a four month cycle. So let’s say hello to QGIS 2.10.Routing with Google is quite cool as the database/network is probably the best currently available. But the terms of services limit the possible usage. So what about OpenStreetMap? By figuring out how to use OSM for routing I found it much easier to get routes into QGIS with OSM compared to the Google way. Check it out….Routing in QGIS was, as far as I know, always dependent on an available network. Either you had some database which was pgrouting enabled, or you had some network and used this via the roadgraph plugin. I would like to show you, how to do routing and path finding via googlemaps and import the path into QGIS. Big advantage: You don’t even have to think about a network…Anita showed some nice examples of tweets in QGIS in 2012. Since then it seemed to be quiet about the twitter-content in QGIS. Yet tweets can be an interesting source of information. Sometimes they can tell you something about the spatiotemporal dimensions regarding a keyword, the digital heartbeat of a defined region and many more. Yet we need to be careful with the data as it is completely biased. But how to get this data stream into QGIS?Since I developed qgis2leaf together with some great supporters we always struggled with sharing a qgis project: we use different layers, different visualizations and so on. It’s not easy to make sure you’re talking about the same. So why not make it possible to export a whole qgs project with one click…When I started to work on QGIS2leaf about one year ago it was a nice idea and my first real dive into Python programming and using the possibilities of pyqgis. So what is the current state and where are we going? Please, come and take a look: Happy Birthday QGIS2leaf!The normal way of getting Landsat data for your GIS projects often was: visit a Landsat data mart like landcover.org, earthexplorer or WIST, search for your area and time and download/order your desired data. Once you’ve done this, you were prepared to add, analyse and publish this data/results with QGIS. Luca Congedo from the blog “From GIS to Remote Sensing” .
To map excel data onto a print- or webmap is one of the most needed and chosen data preparations. Companies and scientists are often highly interested in located table datasets on maps. In this how to I’ll show you, that this job could be done with free and open source software like QGIS.
A few days ago I saw Franz Leonardo’s post on the ArcGIS group on facebook: He visualised wind speed and direction in ArcGIS for a wind map and I thought by myself: let’s do it with QGIS… Here is the tutorial which covers some aspects of interpolation, symbol levels, classification and formulas…QGIS 2.8 (the new “Long Term Release”) was released a few days ago. It is a minor release according to the changelog but it will be supported in this setup at least for the next year: Some good news for all those working in a bigger, administrated environment as it is always a problem to update software in these bigger infrastructures. New features: >1000 issues flagged by static analysis tools fixed new code commits and pull requests are now automatically tests against our testing framework. more responsive browser support for contextual WMS legend graphics custom prefixes for joins creation of…So I came across this nice little project which focussed on trip planning and route over large distances… And there was this nice little post from Nathan Yau at flowingdata.com where he describes the making of great circles from one point to different other points in R and the other example from Anita Graser where she shows how to deal with an Arc in QGIS but using postgis functionality. So what about QGIS itself and a programmatic way? See yourself…
