Answer:
Five accurate data sources map makers can rely on for map making are:
- Esri Open Data Hub
- Natural Earth Data
- USGS Earth explorer
- OpenStreetMap
- NASA's Socieconomic Data Centre
Step-by-step explanation:
1. Esri Open Data Hub has over 250,000 open data sets from over 5,000 organizations worldwide, and is the largest GIS organization in the world. Data types found there are OGC, WMS, GeoJSON and GeoService.
2. Natural Earth Data is a public domain data source best suited for cartographers, and is supported by the NACIS. Physical and cultural raster data, quick start kits (MXD and QGS) files can be found there.
3. USGS Earth Explorer has worldwide satellite imagery and a state-of-the-art user interface. Landsat, Sentinel-2 and land cover, digital elevation models such as NASA's ASTER and STRM are data examples that can be found there.
4. OpenStreetMap possibly has the biggest inventory of buildings in the world, with highly detailed GIS data. High spatial cultural vector data such as buildings and waterways can be found there.
5. SEDAC has a gridded population of the world, including population characteristics, also Global socioeconomic data comes from 15 different themes. Data includes agriculture, climate and health.
