Free GIS Datasets - Categorised List SRTM Tile Grabber Note: This tool doesn't work as of January 2021, because the data paths it pointed to on external mirrors have changed. You can download tiles from CGIAR's website here. This map may still be useful for finding figuring out which file name you're interested in downloading. This interface attempts to ease the pain of downloading elevation data from the Shuttle Radar Topography Mission. Click on red tiles to download their corresponding data. Each tile comes in GeoTIFF format at 90-meter resolution (6000x6000 pixels), from various mirrors I've found on the web. The files linked here are version 4.1 of an effort by the folks at CIAT-CSI to scrub, polish, and remove gaps in the raw SRTM data released by NASA. Any download policies of the respective mirrors apply.
OpenStreetMapData Are you tired of ho-hum cartography advice? OpenStreetMap Data: How to Download Crowd-Sourced OSM Data - GIS Geography What is OpenStreetMap (OSM)? OpenStreetMap is like the Wikipedia of maps. It’s the largest community of mappers in the world who constantly edit the geography of our changing planet. See, the problem with Google Maps data is that it’s proprietary and extremely difficult to obtain. And often other types of detailed data come at great costs. So we needed something open for the world to edit. As “open” is the key philosophy to OpenStreetMap, this is also true for data being “open”.

OpenStreetMap is the data set you need that you didn’t know existed for public consumption. Turns out, that there are several ways to download OpenStreetMap data. My suggestion is Geofabrik because it’s organized by continent, country, and then province or state. And I also prefer downloading OSM data as shapefiles. What types of features are in OSM Data? Building footprints are notably impressive.
European Environment Agency - GIS Data and Maps The pan-European High-Resolution Vegetation Phenology and Productivity product suite (HR-VPP) are provided at a high spatial resolution (10 m x 10 m) with a high repeat frequency. They are derived from the optical Sentinel-2 constellation data (Sentinel-2A and Sentinel-2B) with a revisit time of 5 days. They are generated over the entire EEA39 region (33 member countries and 6 cooperating countries) from January 1 2017 onwards, with a daily, 10-daily and yearly frequency (see below). The HR-VPP product suite contains 3 product groups, 31 product types, 1522 files and more than 900.000 tiles per year, which totals more than 80 Terra Bytes of data, per year. The figure shows the difference in emissions of POPs between 2005 and 2019 This interactive data viewer provides accounts of imperviousness, i.e. land surface sealing status in Europe (EEA39 and EU27+UK) for the year 2018. Historical greenhouse gas emissions from the EU buildings sector show a decreasing trend since 2005.
In the Air How to Download Free Sentinel Satellite Data - GIS Geography Download Sentinel-1 and Sentinel-2 Satellite Data If you want to download Sentinel satellite data, then you’ve come to the right place. One of the most exciting developments in remote sensing at this time is the European Space Agency’s Copernicus Programme. Copernicus’ six Sentinel satellites collects comprehensive pictures of our land, ocean, emergency response, atmosphere, security and climate change to understand the health of our planet. Until very recently, this data has become available to the public at no cost Today, we show you step-by-step how to download Sentinel satellite data: Sentinels Scientific Data Hub In 2014-15, Sentinel-1 and Sentinel-2A were successfully launched from Europe’s Spaceport in French Guiana. One Sentinel scene after the other, data has been rolling out on a user interface called the Sentinels Scientific Data Hub. It’s now available for the public to access. But you will have to hop through a couple of hoops before you can get your fingers on it. What’s Next? Source

ImagePlot visualization software: explore patterns in large image collections What is ImagePlot? ImagePlot is a free software tool that visualizes collections of images and video of any size. It is implemented as a macro which works with the open source image processing program ImageJ. ImagePlot was developed by the Software Studies Initiative with support from the National Endowment for Humanities (NEH), the California Institute for Telecommunications and Information Technology (Calit2), and the Center for Research in Computing and the Arts (CRCA). See your whole image collection in a single visualization. Existing visualization tools show data as points, lines, and bars. Better understand media collections and make new discoveries. Visualize image collections as timelines and scatter plots which display all images in a collection. Visualize change. We include macros which automatically measure various visual properties of every image in collection (or every frame in a video). Visualize image collections of any size. From a few dozens to millions of images.
