### 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.

**Model developer**: Mark Rodrigo
- Chat to Map interfacing.

**Model Architecture**: The model is a QLoRA / Supervised Fine Tuning (SFT)

### Model Input / Output Overview:

Input: Text plus coordinate prompt injection.
Output: **PostGIS spatial SQL**
NOTE: Inputs and outputs are in meters and or geographic decimal degrees WGS 84 coordinates.

| Function  | Question Input  | Geo Input | SQL Execution Output      |
|:---------:|:---------------:|:---------:|:-------------------------:|
| Area      | Area question   | Polygon   | Number - Area sq meters   |
| Centroid  | Center question | Polygon   | Point                     |
| Buffer    | Buffer distance | Point     | Polygon                   |
| Length    | Length question | Line      | Number - Length in meters |

### Example Prompt / Prompt File

<|begin_of_text|><|start_header_id|>system<|end_header_id|>
<p></p>
You are a helpful assistant. You are an expert at PostGIS and Postgresql and SQL and psql.
<p></p>
<|eot_id|><|start_header_id|>user<|end_header_id|>

\### Instruction: Write a PostGIS SQL statement for the following.
<p></p>

\### Input:

<p></p>
{input}

<p></p>

\### Response:

<|eot_id|><|start_header_id|>assistant<|end_header_id|>


### 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.
