Real GIS work for professionals — and a fast, no-jargon way for anyone else to get one thing done. Pick a tool, get a result. No account, no install, no learning curve required to start.
Every category a working GIS practice actually needs — no separate logins, no scattered utilities.
DMS ⇄ Decimal Degrees, plus free-form coordinate parsing.
CSV, Excel, Shapefile → styled KML/KMZ for Google Earth.
Buffer, Clip, Intersect, Dissolve, and 11 more operations.
Bearing, traverse closure, chainage, and 3 more calculators.
Slope, hillshade, contour, NDVI — from DEM and satellite imagery.
Layer viewer, coordinate picker, distance & area measurement.
Draw, upload, and edit points/lines/polygons — with schema-based attributes and 7 export formats.
Shapefile, GeoJSON, GeoPackage, CSV, KML/KMZ, DXF — any format to any other.
Split a polygon into equal-area lots, fixed-width strips, or target-area plots.
Acres, hectares, square feet, plus regional land units like Bigha and Biswa.
Reproject an entire file to any EPSG code — searches the real EPSG registry.
Compose a print-ready map with layers, precise scale, scale bar, and legend.
Shortest path and service area analysis along a line network.
Detect and fix geometry errors — self-intersections, duplicates, invalid rings.
Depression filling, flow direction/accumulation, stream network with Strahler order, and watershed delineation.
Automatic K-means + NDVI/NDWI/NDBI classification, refined with your own samples — or build entirely new classes.
Upload a file, draw on the map, or just type coordinates — whatever you already have.
Every calculation happens on the server, in proper projected units — not approximated in your browser.
Check the result before committing — attributes, styling, and geometry, right in the tool.
Export in the format you actually need — Shapefile, KML, GeoTIFF, DXF, and more.
A GIS professional running a real workflow and someone who just needs to fix one Excel file are using the same platform, built the same way, at the same time.
Hydrology Tools doesn't make you run depression-filling and flow-direction yourself first — pick "Watershed" and the prerequisite steps happen automatically underneath. You ask for the outcome.
Upload data into Vector Analysis and the buffer distance is already suggested from your data's real size — not a generic "100." Type a category like "School" into KML Studio and it picks the actual school icon, not just the next one in a rotation.
Repair a file's geometry, then send that exact result straight into Vector Analysis or KML Studio — no re-downloading, no re-uploading. Most tool sites are separate silos; this one isn't.
Everything runs in your browser — no license, no install, no waiting on IT approval.
Windows, Mac, Linux, or mobile — if it has a browser, it runs SM Datum.
Your data is processed in memory for each request and discarded immediately afterward.
Turn a spreadsheet of coordinates into a styled Google Earth file — no software install.
Vector AnalysisCreate accurate setback or impact zones around any feature, in real-world units.
Raster ToolsGo from a raw multi-band GeoTIFF to a vegetation index map in one pass.
Sagarmekhla GIS Consultancy has worked geospatial problems for government, research, and industry clients directly — every tool on this platform runs the same methods, the same care around projection and unit correctness, that we apply on paid consulting work. The tools aren't a side project; they're a public extension of the same practice.
Parcel, utility, and infrastructure digitization and analysis for planning bodies.
Remote sensing-based vegetation, water, and land-use change analysis.
Traverse computation, boundary reconciliation, and field-to-office data workflows.
Catchment delineation, drainage network extraction, and terrain-based flow modeling.
Sagarmekhla GIS Consultancy delivers custom spatial analysis, remote sensing, and mapping for government, research, and industry — the same standards behind every tool on this page.
