+# Location Proof Protocol v0.1: `locationType`
+
+To ensure location proofs are as versatile as possible, we are giving users / developers the option of creating proofs that adhere to any
+location type.
+
+This requires creating a standardized set of categories for "location types" that include various ways of representing locations such as
+different coordinate systems, H3 strings, geohashes, and more. The purpose of this is to ensure interoperability and clarity in geospatial
+data management, while still offering flexibility for different proof types.
+
+Here is a v0.1 proposed categorization.
+
+### Categories of Location Types
+
+1. **Geographic Coordinates (Lat/Long)**
+   - **Decimal Degrees**: Standard longitude and latitude (e.g., `[-122.4194, 37.7749]`).
+   - **Degrees, Minutes, Seconds (DMS)**: Latitude and longitude in degrees, minutes, and seconds (e.g., `37°46'30" N, 122°25'10" W`).
+2. **Projected Coordinates**
+   - **Universal Transverse Mercator (UTM)**: Uses a series of zones for global coverage (e.g., `10S 551000 4182000`).
+   - **State Plane Coordinate System (SPCS)**: Used in the United States (e.g., `X: 2000000, Y: 500000` in a specific state plane zone).
+3. **Geohashes**
+   - **Geohash**: A hierarchical spatial data structure which subdivides space into buckets of grid shape (e.g., `9q8yyz`).
+4. **H3 Hexagons**
+   - **H3**: A hierarchical hexagonal grid system used for spatial indexing (e.g., `85283473fffffff`).
+5. **Plus Codes**
+   - **Open Location Code (OLC)**: Developed by Google, it's a code that represents an area anywhere on Earth (e.g., `7FG8V4VC+G7`).
+6. **Grid References**
+   - **Military Grid Reference System (MGRS)**: Used by NATO militaries for locating points on the Earth (e.g., `33TWN8382558454`).
+   - **British National Grid (OSGB)**: Used in Great Britain (e.g., `TQ 298828`).
+7. **Place Names / Addresses**
+   - **Postal Address**: Standard mailing address (e.g., `1600 Amphitheatre Parkway, Mountain View, CA`).
+   - **Named Locations**: Known place names (e.g., `Eiffel Tower`).
+8. **What3Words References**
+   - **W3W**: A geocoding system that encodes geographic coordinates into three dictionary words (e.g., ///filled.count.soap).
+
+Formal specification of the location types and how they are represented is in development, and will be documented here.
