Satellite maps and data for any area you choose

NDVI, NDWI, MNDWI, NDBI, SAVI, EVI and NBR from Sentinel-2 (10 m, 2017 to today) or Landsat (30 m, 1984 to today), for one period or every year.

The Sentinel-2 or Landsat bands you choose, listed by number and name, from the clearest image near your date, stacked in your order in one GeoTIFF with a colour map.

Elevation, slope, aspect and hillshade from the Copernicus, ALOS or NASADEM elevation models (30 m).

Lines of equal height every 1 to 100 m, or at a step chosen for your area, with labelled index contours, as a map and as a line file.

Click an outlet to get the catchment, streams by Strahler order, the main channel, morphometric parameters, the hypsometric curve and the time of concentration.

Draw a line, or put points, and get the ground along it: the profile chart and, every 30 m or at the distance you choose, the station, distance, elevation, coordinates and slope of each point, in Excel and on a map. The Copernicus, ALOS and NASADEM elevation models can be compared on one chart.

The peak flow and runoff volume of the catchment above an outlet for storms of 2 to 100 years, by the Rational and SCS curve number methods. Type your own data, or let Geo Tool take the catchment, land cover, soil groups and rainfall from open data; the Excel file shows every step.

Draw a dam across a valley, or click the river and give a height, and see the lake for any water level: its area, volume and depth, the size of the dam and the yearly inflow. Buildings, roads and villages the water would cover are shown in red, so you see what would have to be moved.

Flood, landslide, wildfire, earthquake, drought, land degradation and heat hazard of any area in five classes, from very low to very high. The default factors and weights come from Kaifi Chomani's published studies, with their DOI links; tick other factors and set your own weights, and the map follows at once.

ESA WorldCover (2020 or 2021) and Esri land use maps (10 m, any year from 2017 to 2023), and the JRC history of surface water since 1984.

Daily or monthly CHIRPS rainfall since 1981 for any point you type or draw, as CSV tables with monthly and yearly totals and a chart.

Burned area and severity (dNBR, with your own threshold if you wish), active fires from NASA FIRMS, past fires from MODIS, and earthquakes from today back to 1900 from USGS and EMSC.

Building footprints, roads, rivers, lakes and points of interest from OpenStreetMap and Overture Maps.

Turn your own list of villages, wells or sample sites (Excel, CSV, KML or GPX) into a finished map, with names in English, Kurdish or Arabic on a satellite or white background.

Lengths, areas in m², hectares, km² and dunam, distances and coordinates in degrees and UTM. Every result is its own file: PNG maps with coordinates, scale bar and north arrow, GeoTIFF, GeoPackage, Shapefile and CSV.
