### Model Information |
|
|
|
This model, Llama-3.2-3B-Instruct-Spatial-SQL-1.0, is an 3B, narrow use case, text to spatial SQL, lightly fine-tuned model. In general, its primary use case |
|
is the Natural Language command adaptation of particular geographic spatial functions as normally defined in pure SQL. Data input should be a combination of an English prefix in the form of a question, and a coordinate prompt injection, likely from an active mapping system application coordinate list. Output is PostGIS spatial SQL. |
|
|
|
There are four primary geographic functions released in version 1.0. |

### Examples |
|
**Note 10/6/24 ** |
|
- Centroid and Buffer responses are currently returning as WKT. While technically correct, this is not the desired response, and will be addressed. |
|
</br> Reference - https://postgis.net/docs/ST_AsText.html |
|
- English and Chinese models, etc. currently require the 8b models and or additional fine-tuning for 3b. |
