Satellite imagery is bringing land monitoring to a completely new level. Sentinel-2 data offers 10-20m spatial resolution, 5-day revisit frequency, global coverage and compatibility to the Landsat missions and provides new opportunities for regional to global agriculture monitoring. Monitoring of crop conditions, soil properties and mapping tillage activities, help to assess land use, predict harvests, monitor seasonal changes and assist in implementing policy for sustainable development. Sentinel data can also be used for monitoring the changes of agricultural production and productivity of pastures caused by drought and monitoring the decline of land productivity and soil degradation due to excessive cultivation and pasturage and improper irrigation.
Agricultural maps enable provision of independent and objective estimates of the extent of cultivation in a given country or growing season, which can be used to support efforts to ensure food security in vulnerable areas.
Examples of applications and services using Sentinel Hub:
“A web based platform designed for farmers, consultants and other professionals that want to excel at decision making in agriculture and the environment.”
“Services for early detection of Southern Africa’s invasive pest species, pest monitoring, and precision agriculture.”
NDVI Max Service
The NDVI Max service is a simple, yet powerful tool with various application possibilities in the framework of land monitoring and land use.
Sentinel app for Android
The Sentinel-2 NDVI Maps application presents the current NDVI* map based on Sentinel-2 data, provided by Copernicus. The following imagery layers are available:
- Open Street Map layers for general browsing
- Sentinel 2 NDVI imagery
- Sentinel 2 EVI imagery
- Sentinel 2 true color imagery
- Sentinel 2 false color imagery
- Sentinel 2 layers have a minimum zoom level limit.
They will only show on high zoom levels. This means that while you may zoom in as much as you want, it will not be possible to view very large areas. Sentinel 2 layers also display only the latest image data with at most 20% cloud coverage. The in-app payment will allow access to the following advanced features for one year after purchase:
- Sentinel 2 layers have a minimum zoom level of 12 which corresponds to four times the viewable surface area of the free version.
- Time shift functionality allowing you to choose which dates the imagery comes from by week.
The app is available for download on Google Play :
* The Normalized Difference Vegetation Index (NDVI) is an index of plant “greenness” or photosynthetic activity, and is one of the most commonly used vegetation indices. Vegetation indices are based on the observation that different surfaces reflect different types of light differently.
