CoordMap

CoordMap is a collection of free browser tools for working with locations, GPS coordinates, maps, elevation, distance, and related geographic data. Its home page acts as a common starting point for tasks that would otherwise require several unrelated websites. A user can search for a place, paste a latitude and longitude pair, ask the browser for the current location, or open a specialized calculator. The tools run without requiring an account for core use, which makes the site practical for quick lookups and one off conversions.

The latitude and longitude finder can turn an address or a clicked map point into coordinates. The reverse workflow turns coordinates back into a street address when the geocoding data supports it. A world map lets users search or click to inspect places, while My Location shows the browser's current coordinates and address after explicit permission. CoordMap displays coordinates in WGS84, also known as EPSG 4326, and includes converters for decimal degrees, degrees minutes seconds, UTM, and MGRS. It doesn't apply the regional GCJ 02 or BD 09 offsets used by some map services.

Measurement tools cover both simple and multi-point work. Users can calculate straight line distance between places, add several points to a route style measurement, or draw points around a parcel to estimate area and perimeter. The elevation tool accepts an address or coordinate pair and returns an estimated height above sea level. That result comes from a local digital elevation model with roughly one kilometer resolution, so it is useful for orientation and comparison but not for surveying, construction, or any decision that needs precise ground measurement.

The site also brings contextual tools into the same interface. Sunrise and sunset pages can show solar times, moonrise, moonset, and moon phase for a location. Weather data is fetched separately when a user opens a weather view. Time zone, city, country, nearby place, public IP, and IP or domain lookup pages broaden the collection beyond coordinate conversion. IP locations are approximate at the city or regional level, as is normal for GeoIP data, and shouldn't be treated as a device's exact physical position.

CoordMap is transparent about the sources behind the results. Its map uses MapFirst tiles through MapLibre. Place and address searches use LocationIQ with Nominatim as a fallback, weather comes from WeatherAPI, and elevation is evaluated against a local digital elevation model. These sources have different limits and accuracy. Geocoding providers enforce fair use quotas, so searches may be rate limited, and a cached result may be used to reduce upstream requests. The site labels elevation as an estimate rather than presenting it as survey quality.

Privacy behavior depends on the tool. Browser geolocation starts only after the user clicks a location action and grants permission. Distance from the current position can be calculated in the browser, but address searches or reverse geocoding may send the query or coordinates to LocationIQ or Nominatim. Weather views send coordinates to WeatherAPI, and map tile providers receive ordinary requests tied to the visible map area and network address. Geocoding results may be cached. Only locations a signed in user explicitly shares become reachable through a public share link, while optional account history is private by default.

The broad tool set works well for travelers checking daylight, developers validating coordinate formats, property owners estimating a rough area, students exploring map concepts, and anyone who needs to move between an address and latitude or longitude. It is especially handy when the task is small enough that installing GIS software would be excessive. It is not a professional geographic information system, route optimizer, surveying package, or guaranteed source of current legal boundaries. Its strength is fast access to familiar global map utilities through one consistent site. CoordMap is free to use, and the public site doesn't present a paid plan. Core geocoding, elevation, map, conversion, and current location tools work without signing in. An account is needed only for optional private history and share management features. The tradeoff for free access is that upstream quotas can limit repeated searches and some results are necessarily estimates. For casual and lightweight professional lookups, the service offers a useful amount of geographic context with clear source notes and sensible controls around browser location permission.
