Geo Tool 1.5.0

Download GeoTool-Windows-x64.zip below, unzip it (right-click → Extract All, and wait until it has finished), then double-click GeoTool.exe. No installation, no account.

• Dam and lake: on the Map tab, draw a dam with the Line tool across a valley (from one hillside to the other, over the river) — or put a point on the river and give the dam height, and Geo Tool draws the shortest dam line across the valley that holds the water — then press 🌊 Dam and lake…. Geo Tool fills the valley behind the dam the way water fills it. Move the water level and see at once the lake, its area (km², ha, dunam), volume and depth, the height and length of the dam and the earth fill it needs, and the highest level the dam can hold (above it water would flow around the end of the dam or over a low pass into another valley)
• What goes under water, in red: buildings, roads, villages, schools, mosques and other places inside the lake are coloured red on the picture and the map (to be moved), with their numbers and the farmland and other land under water; lists of them are saved as CSV
• Saved for the dam: a lake map on the satellite image with water depth and contour lines, the elevation–area–volume curve and table (every 0.5 m), the ground along the dam, a 3D view, the lake and dam as GeoPackage, GeoJSON, KML (Google Earth) and Shapefile, water depth and flooding-level GeoTIFFs, and a README that explains the method and its limits. Optional: the yearly inflow from CHIRPS rainfall on the catchment
• Contour lines: a new item in Download data (Terrain and water): contour lines every 1 to 100 m (or automatic) as a map with labelled index lines and as a line file
• A screening tool for teaching and first studies: the 30 m elevation data has errors of a few metres, and a dam also needs a survey, geology and hydrology studies

• Band composite: a new sub-tab in Download data. Choose Sentinel-2, Landsat 8–9 or Landsat 4–7, tick the bands (each shown with its number, name, wavelength and pixel size) in the order you want, or pick a ready combination (natural colour, false colour, agriculture, short-wave infrared, urban), and choose a date. Geo Tool uses the clearest image of that day, or the nearest clear day, and saves one GeoTIFF with your bands in your order (surface reflectance 0–1; the Landsat thermal band as surface temperature in °C), a colour map of the first three bands and a table of the bands
• Rainfall at a point (CHIRPS): type a point or use a point drawn on the map, choose the dates and daily or monthly values; you get CSV tables (every day or month, monthly and yearly totals) and a chart. CHIRPS v3.0 from the Climate Hazards Center (UC Santa Barbara), 1981 to about last month; daily values up to 5 years per run (about 5 minutes per year, as the server asks for slow reading). Rainfall alone needs no area
• Land cover year: choose the ESA WorldCover year (2020 or 2021) and the Esri land use year, or two years to get every year between them (2017–2023)
• Burned area — your own threshold: under "Burned area and severity (dNBR)" you can write the dNBR value above which a pixel counts as burned. 0 = automatic (0.10, the USGS value). Write a lower number (e.g. 0.05) when light grass or crop fires are not completely found, or a higher one (e.g. 0.20) when dry or harvested fields are shown as burned; the severity classes, the burned-area table and the maps follow your number
• Settings follow your ticks: only the settings needed by what you ticked are active, the others are grey, and every sub-tab shows how many items are ticked in it

New in 1.3

• Point map: turn your own list of places into a finished map. On the Map tab, import your points (or draw them) and press 📍 Point map…: choose a title, a satellite or white background, names next to the points or numbers with a list of names, colours by a column (e.g. type or district), point size, A4 landscape or portrait and 300 / 600 / 700 dpi. The map shows a north arrow, scale bar, coordinate grid, legend and a small inset map, and the points are also saved as CSV (decimal, DMS and UTM), KML (Google Earth), GeoJSON and Shapefile
• Import Excel (.xlsx) and GPX files, and coordinates written in degrees-minutes-seconds (36°15′30″N); column names in English, Kurdish or Arabic (name / ناو, latitude / پانی, longitude / درێژی …) are recognised; other columns are kept
• Names in Kurdish and Arabic are written correctly on the maps (Noto Sans Arabic font)
• Points_template.csv next to GeoTool.exe shows how to arrange your points
• GeoTool.exe is the last file to come out of the zip, and the program explains clearly if it is opened before unzipping has finished

Also in Geo Tool (since 1.2): satellite indices (NDVI, NDWI, MNDWI, NDBI, SAVI, EVI, NBR), true and false colour images, terrain (Copernicus, ALOS or NASADEM DEM: elevation, slope, aspect, hillshade), watersheds with streams and morphometry, land cover and surface water, burned area and severity (dNBR), fires now and past, earthquakes now and archive, buildings, roads, rivers and points of interest, drawing and measuring (coordinates, distances, areas in m², ha, km² and dunam). Every map carries the credit its data provider asks for; the licences of the open-source parts are in THIRD_PARTY_LICENSES.txt.
