## Installation:

1. Download ShrimpGIS. Available on [Food4Rhino](https://www.food4rhino.com/app/shrimpgis)

2. Check if downloaded .zip file has been blocked: right click on it, and choose Properties. If there is an Unblock button click on it, otherwise it is OK. Unzip it.

3. Follow 'README.txt' instructions.

## Requirements:

* Rhino 6

## Dependencies:

* pyshp

* utm

* pygeoj

## Features:

* Transformation of points, surface/breps, curves, meshes into Esri shapefile entities.

* Discretization for curves and surface/breps.

* Transformation of Esri shapefile entities into points, surface/breps, curves.

* Extraction of fields.

* Transformation of points, surface/breps, curves into Geojson entities.

* Transformation of Geojson entities into points, surface/breps, curves.

* Merge Multiple geojson in to one geojson

* Write Esri ASCII Raster file.

## Limits v.1.0.3:

* Rhino document has to be in meter

* Only WGS84 (EPSG:4326) reference system is supported. I suggest you use a GIS software for reprojection (e.g. [QGIS](https://www.qgis.org/en/site/)).

* Shapefile read component supports following GIS types:

  * POINT

  * POLYLINE

  * POLYGON

  * POINTZ

  * POLYLINEZ

  * POLYGONZ

* Geojson components support only 2D FeatureCollection.
