# Platforms & Tools

> Digital mapping tools such as GIS technologies and Google Earth are founded within western epistemologies and perpetuate the colonial ‘gaze’ and power inequity. These maps are far from neutral: ‘The problem with positioning GIS as software that simply gathers empirical data and presents it as fact is that such ‘scientific objectivity’ is typically situated and privileges those in power’ ([Farman](https://www.semanticscholar.org/paper/Localizing-landscapes:-a-call-for-respectful-design-Syme/45d7844e449a644556cbc8e709a3a8756b32376b)).&#x20;

So it's important to remember that these platforms are simply tools. Tools that need to be used in responsible ways. Below you'll find a list of some of the more common GIS platforms as well as the features relevant for responsible GIS practices.

Highly customizable and versatile, QGIS supports various vector, raster, and database formats and functionalities. It allows users to create rich maps and complex spatial analyses without the cost of proprietary software. The platform's strong community support and continual updates ensure that it remains at the cutting edge of GIS technology, providing a reliable and accessible option for anyone looking to utilize GIS in their projects, whether they are in academia, government, or the private sector.

#### More Info:

* Multiple plugins available to implement responsible GIS including plugins for [data protection](https://plugins.qgis.org/plugins/GeoPriv/), [differential privacy](https://plugins.qgis.org/plugins/differential_privacy/#plugin-about), and [normalization](https://plugins.qgis.org/plugins/area_weighted_average/).
* QGIS has support for approximately [7,000 known CRSs](https://docs.qgis.org/3.34/en/docs/user_manual/working_with_projections/working_with_projections.html).
* Forms a part of [OsGeoLive](https://live.osgeo.org/en/index.html), a self contained open source GIS solution that "allows you to try a wide variety of open source geospatial software without installing anything."

### ArcGIS

<mark style="background-color:blue;">Great for those looking for an all-in-one enterprise level tool</mark>

ArcGIS is a suite of GIS software developed by Esri, designed to facilitate the creation, management, analysis, and sharing of geographic information across various industries. This platform includes applications such as ArcGIS Pro for spatial data management and analysis, ArcGIS Online for cloud-based mapping, and ArcGIS Enterprise for secure, scalable geospatial applications. Additional specialized tools like ArcGIS Field Maps and ArcGIS StoryMaps enhance field operations and storytelling with maps, respectively.&#x20;

#### More Info:

* Esri UK has [committed to halve greenhouse gas emissions and reach net-zero emissions before 2030](https://www.esriuk.com/content/dam/distributor-restricted/esriuk-com/legal/carbon-reduction-plan/esri-holdings-carbon-reduction-plan-2021.pdf).&#x20;
* Coordinate systems: Supports over [2,000 systems](https://desktop.arcgis.com/en/arcmap/latest/map/projections/pdf/geographic_coordinate_systems.pdf).
* Esri has recently developed the experimental "[Geospatial Virtual Data Enclave](https://www.esri.com/about/newsroom/arcnews/dealing-with-geoprivacy-and-confidential-geospatial-data/)" aimed at facilitating the work of those who need to share yet protect their data.

### [**CARTO**](https://cartodb.com)&#x20;

<mark style="background-color:blue;">Great for those looking for a custom solution.</mark>

CARTO, is a cloud-based platform that provides GIS and web mapping tools for display in a web browser. It allows users to store, manage, and analyze spatial and non-spatial data. CARTO is designed to make complex spatial data more accessible and actionable for businesses, researchers, and governments. The platform supports various forms of data visualization, such as maps, charts, and tables, enabling users to discover and extract insights from large datasets.&#x20;

**More info:**

* [Coordinate systems](https://github.com/Vizzuality/CartoDB-Tutorials/blob/master/drafts/projections.md): Converts and stores all geometries in WGS84. For Google Maps or Leaflet, they use a different projection called Web Mercator.&#x20;

### [**Mapbox**](https://mapbox.com)&#x20;

<mark style="background-color:blue;">Great for those looking for a custom solution.</mark>

Mapbox provides mapping, location, and spatial analysis tools to developers, businesses, and organizations.

The platform is designed to be flexible and scalable, supporting everything from small projects to enterprise-level solutions. Mapbox emphasizes user privacy.

**More info:**

* [Coordinate systems](https://docs.mapbox.com/help/glossary/projection/): Mapbox Tiling Service and Mapbox SDKs for mobile and web accept GeoJSON that follows the GeoJSON standard for a geographic coordinate reference system equivalent to OGC:CRS84, using the WGS84 datum, decimal degrees, and longitude and latitude units (in that order). The Mapbox Uploads API accepts data inputs in a variety of formats and projections.
