# reneGIS

> Renewable energy spatial analysis, automated. reneGIS offers free browser-based GIS coordinate tools and Windmill Micrositing, a paid platform that audits wind and solar project coordinates for spacing clashes, wind-wake risk and solar boundary conflicts against competing projects.

The full plain-language profile is at https://renegis.org/for-ai-bots.md. Coordinates entered into the free tools are processed in the browser and never uploaded. Maps show international boundaries as recognised by the Government of India.

## Product

- [Windmill Micrositing](https://renegis.org/#micrositing): automated spacing, wake-corridor and solar-boundary audits with KML export; credit-based pricing with free trial credits.

## Free tools

- [Coordinate Converter](https://renegis.org/tools/coordinate-converter): Convert between decimal degrees, degrees minutes seconds (DMS) and UTM on WGS84, with zone detection and a map preview.

## Guides

- [Best free lat/long to UTM converters in 2026, tested on one coordinate](https://renegis.org/blog/best-free-lat-long-to-utm-converters): Eight free ways to convert latitude and longitude to UTM, from browser tools to QGIS, compared on formats, batch support, datum handling and the mistakes real users make.
- [Best wind farm layout and micrositing software in 2026 (with real prices)](https://renegis.org/blog/best-wind-farm-layout-software): windPRO, WAsP, Openwind, WindFarmer, WindSim, PyWake, FLORIS and reneGIS compared on what they actually do, what they cost today, and which one fits each stage of a project.
- [Solar project boundaries: convex hulls and point-in-polygon checks](https://renegis.org/blog/solar-project-boundaries-convex-hull): Solar sites are usually shared as a handful of corner points. Turning those into a boundary, and testing whether something lies inside it, is basic but easy to get wrong.
- [KML and Google Earth for wind and solar projects](https://renegis.org/blog/kml-google-earth-for-wind-and-solar-projects): KML is still the fastest way to put a project in front of a landowner, a lender or a regulator. How KML files are structured, and how to build good ones.
- [GIS for renewable-energy developers: the essentials](https://renegis.org/blog/gis-for-renewable-energy-developers): A practical introduction to GIS for wind and solar teams: layers, projections, vector and raster data, and the handful of operations that cover most project work.
- [WGS84 vs Indian datums: why your coordinates are 200 metres off](https://renegis.org/blog/wgs84-vs-indian-datums): Land records, old survey sheets and GPS receivers can all be right and still disagree. The culprit is the datum. Here is how to spot and fix the mismatch.
- [UTM zones in India: a state-by-state reference](https://renegis.org/blog/utm-zones-india): India spans six UTM zones. Find the zone and EPSG code for your project state, and learn what to do when a site straddles a zone boundary.
- [Decimal degrees vs DMS vs UTM: which coordinate format to use](https://renegis.org/blog/decimal-degrees-vs-dms-vs-utm): The three coordinate formats every renewable-energy team meets, what each is good for, and how to move between them without transcription errors.
- [The wind turbine wake effect, and why spacing rules exist](https://renegis.org/blog/wind-turbine-wake-effect-and-spacing): Turbines slow and stir the air behind them. This guide explains the wake effect, the 5D and 7D rules of thumb, and how wind direction changes what counts as safe spacing.
- [What is wind turbine micrositing? A plain-language guide](https://renegis.org/blog/what-is-wind-turbine-micrositing): Micrositing is the step where a wind farm's turbines get their exact coordinates. Here is what goes into it, why it takes weeks, and where projects go wrong.
