![]() ![]() QGIS has multiple ways to perform interpolation. In QGIS, the raster calculator tool performs map algebra with a little less math and trigonometry functions. Other options are to filter (reclass or extraction toolsets) or simplify data (generalization toolset). The Spatial Analysis tools also offer specialized tools for groundwater, hydrology, and solar radiation. Whether it’s simple math (map algebra and conditional toolset), statistics (multivariate, neighborhood, or zonal statistics), or generating value surfaces (interpolation, density, or overlays),ĪrcGIS raster-based tools are rock-solid. The Spatial Analyst extension packs the most punch for raster data manipulation. Raster processing in both QGIS and ArcGIS are crazy, stupid useful READ MORE: 13 Free GIS Software Options: Map the World in Open Sourceĩ. This makes QGIS a dominant winner in this category. It’s like a bad horror movie with the inconvenient 999999 error. ![]() But in the end, you really are licensed to geoprocess in ArcGIS. QGIS is working on its geoprocessing framework which is already impressive. There’s tool integration with GRASS GIS and SAGA GIS, which gives you the necessary horsepower at your disposal to solve almost every geospatial problem. Same as the symmetrical difference tool, which isn’t available with a basic ArcGIS license. The erase tool is readily available in QGIS in the Vector Analysis toolbox. (You could use the free trial of ET GeoWizards). If there are no available advanced licenses, it means you can’t use the erase tool. ![]() If you want to use the erase tool in ArcGIS 10, you’d have to turn on the advanced license. Open source QGIS software does not limit which tools can be used. An advanced license gives you access to everything. But your license level determines which tools you can use in ArcGIS.Ī basic license still gives you access to a large number of powerful tools. QGIS is the open source hero.ĪrcGIS has a very good geoprocessing framework. ArcGIS is the villain forcing you to connect to your license. “Licensed to geoprocess” sounds like a really bad movie. READ MORE: The Ultimate List of GIS Formats – Geospatial File Extensions (Because setting custom delimiters in QGIS is even better than Microsoft Office.)Īnd instead of poring over piles of conflicting and confusing GIS formats, simply consume it with QGIS. Instead of wasting time trying to add space-delimited files, the QGIS interface lets you roll it in 24 hours a day. Instead of pounding the pavement to load your NetCDF files, QGIS will consume it for YOU. But the list goes on for GIS format consumption… ENC, shapefile, geodatabase, MapInfo formats, Microstation file formats, AutoCAD DXF, SpatiaLite, Oracle Spatial, MSSQL Spatial databases, WellKnownText (WKT)… QGIS uses the GDAL/OGR library to read and write GIS data formats. It’s cutting edge when it comes to consuming data. I’ll link to all the posts below when they come out.ArcGIS has broken more hearts than anyone for consuming data. They will come out with new versions and (hopefully) more features to make our lives easier. The rest of the series will include (eventually) everything you can do with Basecamp. There are some limitations and things you’ll need to pay for but if you use your GPS regularly it’s worth it. Garmin Basecamp is far easier to use, nicer on the eyes and has better features.Īnything you want to do with your GPS software you can probably do with Basecamp. MapSource is still around but you probably don’t want to download it since a much nicer program has replaced it. ![]() If you’ve had a Garmin for a while you might remember MapSource, a clunky program for loading maps and tracks onto Garmin GPS. Garmin’s GPS software is called Basecamp. Follow these and you’ll spend less time fiddling around with Basecamp on the computer and more time outside hiking. This is the first post in a series on the features of Garmin Basecamp and how to use them. Garmin is one company that makes excellent GPS and they have a great piece of software to help you get the most of that high-tech little gadget in your pocket. Knowing which streets to take to an address is great if you’re driving but how do you follow the maze of logging roads and trail networks through the woods to exactly the spot you want to go? Trail GPS and the software that comes with it can help you there. If you own a smartphone, you already have a gps in your pocket. GPS are becoming so popular these days with avid outdoors people and folks cruising around cities. ![]()
