KSA-GRF17 Coordinate Converter for Maps

Convert Google Maps locations to approximate KSA-GRF17 geographic and UTM coordinates, including manually selected 2D map points.

KSA-GRF17 Coordinate Converter for Maps Convert Google Maps coordinates from WGS 84 to approximate Saudi Arabia Geodetic Reference Frame 2017 (KSA-GRF17) coordinates. KSA-GRF17 Coordinate Converter for Maps is a lightweight Chrome extension designed for surveyors, GIS professionals, geospatial engineers, researchers, students, and anyone working with geographic coordinates in Saudi Arabia. MAIN FEATURES 1. WGS 84 to KSA-GRF17 Conversion - Convert Google Maps latitude and longitude to approximate KSA-GRF17 geographic coordinates. - Display converted coordinates in decimal degrees. - Use the inverse of the registered EPSG:9383 coordinate transformation. 2. KSA-GRF17 UTM Coordinates - Display projected coordinates as Easting and Northing in metres. - Automatically select the applicable UTM zone based on longitude. - Display the corresponding coordinate reference system information. 3. Select Locations on Google Maps - Extract coordinates from supported Google Maps locations and URLs. - Select unnamed locations using the built-in 2D map point picker. - Display WGS 84 and KSA-GRF17 coordinates for comparison. 4. Manual Coordinate Conversion - Enter WGS 84 latitude and longitude manually. - Convert coordinates without searching for a location. 5. Easy Coordinate Copying - Copy converted coordinates for use in GIS software, reports, and other applications. WHO IS IT FOR? - Land surveyors and geodetic professionals - GIS and remote sensing specialists - Civil engineers and infrastructure planners - Geospatial researchers and students - Professionals working with Saudi Arabian spatial reference systems IMPORTANT ACCURACY INFORMATION The extension provides approximate coordinate transformations and is intended for general mapping, educational use, preliminary analysis, and coordinate reference. Google Maps coordinates do not normally include a coordinate epoch. The extension does not implement a time-dependent local deformation model, and map point selection may introduce additional positional uncertainty. Results must not be treated as certified survey coordinates or used for cadastral, legal boundary, engineering control, or other precision-critical applications without independent verification.
