This topic specifies the attributes that are required to successfully upload geojson as evaluation, constraints, impacts and as a diagram.

It is recommended that you first review the general [checklist of data](https://community.geodesignhub.com/t/a-checklist-of-all-data-for-your-project/46) that are required and also a [step-by-step guide](https://community.geodesignhub.com/t/step-by-step-guide-to-setting-up-data-for-your-project/45) to preparing your dataset.

#### Projection

If a evaluation, impact, constraints or a diagram is created in GIS, then it has to be re-projected in [WGS 1984 / EPSG 3857](http://epsg.io/3857) projection.

#### Evaluation Map

For evaluation maps every feature in the file should have a attribute called: areatype and it should be one of the following five values, a detailed guide for evaluation map colors (and meaning) is [here](https://community.geodesignhub.com/t/evaluation-map-color-codes-on-geodesign-hub/56).

For evaluation maps every feature in the file should have a attribute called: areatype and it should be one of the following five values:

- red
- yellow
- green
- green2
- green3

The red depicts Existing, yellow depicts “Not Appropriate”, green is “Capable”, green2 is “Suitable” and green3 is “Feasible”

#### Impacts Map

For impact maps every feature in the file should have a attribute called: areatype and it should be one of the following five values:

- orange
- yellow
- purple
- purple2
- purple3

#### Constraints

For Constraints, all features need to have a “areatype” and it has to be the following:

- constraints

#### Boundaries

For Boundaries, all features need to have a “areatype” and it has to be the following:

- boundaries

In addition, you can have a additional attribute called “bname” that has the text of the name of the polygon. Boundaries are administrative / political / jurisdictional boundaries within the study area and a free text name field called bname. This can be name of the county etc.

#### Diagrams

For diagrams, the GeoJSON should have empty properties and especially there should be no “areatype” property.

#### Sample Downloads
