In order to access satellite images of your fields, get the weather forecast and other data, you need to add fields to your account first. There are several available options:

  • Draw field on map
  • Upload fields
  • Custom upload (contact us)

Start by clicking +ADD FIELD located in the right bottom corner of your screen.

how to add fields

A window with available options should pop up.

select field adding option

Upload fields

This option allows you to upload files containing pre-drawn field contours to the system. Currently, EOSDA Crop Monitoring supports 4 different format types: .shp.kml.kmz.geojson.

You can either drag-and-drop files onto the web page or click Add your fields.

alternative way of uploading fields

As soon as the field contours appear on the map along with the field card data in the right sidebar menu, click ADD TO MY FIELDS to complete the operation.

Or you can click Cancel (located just below the ADD TO MY FIELDS button) to abort.


A modal window will offer you two choices:

  • SAVE AND CONTINUE. Press this button to automatically add the uploaded field to the list.
  • DELETE AND CONTINUE. Hit this button if you don’t want to add the uploaded field to the list.


Add more information about the newly uploaded field to ensure maximum efficiency of monitoring.

  • Field Name (for your convenience)
  • Group Name (to better organize your fields in the list)
  • Crop Rotation data* (to manage your fields by the crop name, sowing date, and season.

*Accurate monitoring of vegetation development depends on the correctness of crop rotation data.

Error types

The .prj file responsible for the coordinate system is missing, please add it and re-upload

The file cannot be uploaded because EOSDA Crop Monitoring cannot determine the coordinates for the fields in the file.

The .shp file requires a .prj file which contains the source product’s coordinate system type.

File format is not supported. Please use formats .shp, .kml., .geojson or zip archive containing the .shp, .shx, .dbf files.

Check the file format, you may be uploading an invalid format or there is an invalid file in the .zip archive

Overview of file formats that can be uploaded in the system:

  • SHAPE FILE: A .shp is the main file where the field geometry is stored, it is mandatory. .shx is the index file where the index of the geometry of the fields is stored, it is mandatory. The .dbf file is a table that contains the attributes of the fields (field name, culture, etc.), it is mandatory. Equally important is the .prj file which stores information about the coordinate system.
  • KML FILE: A .kml is a file that contains all the elements of a layer or map – object geometry, conventions, descriptions, attributes, images, and other valuable information.
    Note that only the object geometry (polygon shape made of minimum 3 points) can be uploaded into EOSDA Crop Monitoring.
  • GEOJSON: The .geojson format can store primitive types of geographic object descriptions, such as: points (addresses and locations), lines (streets, highways, borders), polygons (countries, states, parcels of land). This file can also store the so-called multitypes which are an amalgamation of several primitive types. Note that, among all the objects contained within this file, only polygons can be uploaded into EOSDA Crop Monitoring.
  • ZIP FILE: You can use a .zip archive to upload files that are part of the shapefile structure, specifically .shp, .shx, .dbf, .prj.

Polygons were not found in the file. Note that separate lines and dots are not supported. Only polygons are recognized by the system.

This error occurs when the file you’re trying to upload is not a polygon shape but alabel, a point, a photo, a line, a road or some other unsupported element.

On EOSDA Crop Monitoring, you can only upload the files containing a polygon shape, i.e. an object in which there are at least three connected coordinate points all connected to each other.

File size exceeds 10 Mb. Split it into smaller files

The error occurs when the file that’s being uploaded exceeds 10 Mb. You can solve the problem by archiving the file in .zip, if it is a shape file. If .zip, .kml or .geojson files exceed 10 Mb,, – the most likely explanation is that there are too many objects (fields) contained within the file, and it is better to re-save these fields from your source by distributing them among 2 or more files.

The field has intersecting contours which are not supported, please fix it

This error tells you that the contours of some of the fields contained within the file overlap (intersect or cross each other), which does not allow for polygons to be correctly created on EOSDA Crop Monitoring. You need to review your fields and their contours at the source from which you are exporting them.

The field exceeds 10,000 ha / 24,710 ac, please resize it or draw a new one

The error occurs when the area of the field whose contours you are trying to upload as a polygon shape is larger than 10,000 hectares or 24,710 acres. You need to edit the contours of the polygon at the source or draw the contours manually on EOSDA Crop Monitoring.

Draw field

The Draw polygon option is employed to contour and add your field to the map.

how to draw your first field

After it’s done, click the SAVE TO MY FIELDS button and give the new field a name, select crop name, sowing date, and season of its cultivation. Then click SAVE to add a field to your Field List.

Field right sidebar menu section

Utilize the field right sidebar menu section to track, review or change activities related to your field with the features designed in EOSDA Crop Monitoring which are Edit field, Crop rotation, Weather today, and Scouting tasks.

Edit field

You can edit your fields whenever you need by going to a three dots menu, then Edit on your Field List.

Crop rotation

Crop rotation data displays historical crop types that used to grow on the field as well as the current growing crop type. This information is extremely useful. For instance, sugar beet planted on the same field two years in a row can cause diseases of the crops that’ll grow there afterwards. Correct crop rotation data includes 3 components: name of the crop, sowing date, and the season when the crop was or is going to be harvested.

edit crop rotation

Note: It is necessary you click on the exact sowing date in the calendar box. Make sure the selected date looks blue in the calendar. 

Weather today

Log in every morning to follow the weather:

  • Temperature
  • Wind speed and direction
  • Humidity
  • Clouds
  • Precipitation

This will help you stay up-to-date and react to changes in a timely manner.

E.g. You’ve planned to apply fertilizer and it is going to rain.

Scouting tasks

In order to send a scout to the field, you should create a scouting task. This task is automatically sent to the mobile application where a scout can pick it up for further execution. To perform the action, click the + ADD NEW TASK button at the bottom of the Task list or assign a task by selecting one of your fields.

how to add scouting task via monitoring

Drop a pointer on the area you want to inspect and the New task window pops up. It contains the preview of your field with a pointer and field coordinates. Fill in the appropriate boxes with Task name, Description, and Assignee, and click SAVE. Once it’s done, the task immediately appears on your task list, as well as on the mobile application connected to your account.

Currently we use Sentinel-2 sensor and satellite images with no more than 60% cloudiness. In this way, the collected statistics includes representative selection and excludes outside factors.


Below are the most commonly used vegetation indices that are presented in EOSDA Crop Monitoring:

NDVI or Normalized Difference Vegetation Index

NDVI is calculated according to the way a plant reflects and absorbs solar radiation at different wavelengths. The index allows for identification of problem areas of the field at different stages of plant growth for timely response. Pay attention to the areas where NDVI values differ considerably. For example, the areas of a field that have an extremely low NDVI rate may indicate problems with pests or plant diseases; and the areas with an abnormally high NDVI signalize the occurrence of weeds.

NDRE or Normalized Difference RedEdge*

NDRE is an indicator of photosynthetic activity of a vegetation cover used to estimate nitrogen concentrations in plant leaves in the middle and at the end of a season. It allows you to detect the oppressed and aging vegetation and is used to identify plant diseases. It also makes it possible to optimize the timing of the harvest.

*The red-edge band is a narrow band in the vegetation reflectance spectrum between the transition of red to near infra-red.

MSAVI or Modified Soil-Adjusted Vegetation Index

MSAVI allows you to determine the presence of vegetation in the early stages of emergence when there is a lot of bare soil. The index minimizes the effect of bare soil on the display of vegetation maps. Based on the index, you can build maps for differential fertilizer application in the early stages of crop growth.

ReCI or Red-edge Chlorophyll Index

ReCI is an index of photosynthetic activity of a vegetative cover, sensitive to the content of chlorophyll in leaves. Since the level of chlorophyll is directly related to the level of nitrogen in the crop, the index allows you to identify the areas of the field that have yellow or faded leaves, which may require additional fertilizer application.

Currently, one moisture index is available on the platform:

NDMI or Normalized Difference Moisture Index

NDMI describes the crop’s water stress level and is calculated as the ratio between the difference and the sum of the refracted radiation in the near-infrared and SWIR spectrums. The interpretation of the absolute value of the NDMI makes it possible to immediately recognize the areas in which the farm or field is experiencing water stress. NDMI is easy to interpret: its values vary between -1 and 1, and each value corresponds to a different agronomic situation, independently of the crop

NDVI, NDRE, MSAVI, ReCI, NDMI are indices that can be selected either from the left drop-down menu or the three-dots menu on the small panel above the analytics window.

To expand the statistics to check the index of your field, use the small panel above the analytics window. Statistics can be displayed in hectares or percentage.

values of vegetation indices


We do not upload satellite images with more than 60% cloudiness. When using an index, there should be no outside factors that can influence the whole picture. With this said, we consider the possibility of getting value from 60% cloudy images as a positive one. Statistics displays in ha and percentage. Clouds are displayed as a white mask over the field.

Basic Layer: Elevation map

Elevation map is a digital model that visualizes differences in elevation across your field. The model allows agronomists to detect potentially problem areas of the field:

  • flood hazards
  • limited access to water
  • erosion risks

and other types.

Combined with other data (NDVI, productivity map, and others), elevation map helps to identify and eliminate factors which impede vegetation development.

This model also allows you to measure field area with more accuracy. It is crucial to know the exact area of your field to correctly calculate the amount of seedlings, fuel, and time required to perform field activities.

How to find the elevation map?

By default, you see the NDVI values of your field on the map. In order to see the differences in elevation, click on the index panel and select the elevation map from the drop-down list.

select elevation map

Now you can see the differences in elevation across your field.

elevation map in action

Elevations are visualized as different hues, from dark-green low areas to dark-red high areas. Moreover, by hovering over the map, you will be able to see the actual altitude of any point on your field as meters above the sea level.

elevation values

To better understand the elevation variations of your field, check how the color scheme correlates with the elevation values. Just click on the expand icon in the lower right corner.

accessing temperature and moisture data


Min temperature curve shows the history of minimum temperatures occurring in your field over a period of time. Whenever this curve crosses the Cold stress mark at -6°C, your winter crops are at risk of damage or failure. Track the curve and react when it is approaching the cold stress. Over time, you can build trends based on this graph to better protect your crops.

cold stress threat detection

Max temperature curve represents the history of maximum temperatures in the field over a period of time. Whenever it crosses the Heat stress mark at +30°C, your crops are at risk of experiencing drought conditions. Track the curve and react when it is approaching the heat stress. Over time, you can build trends based on this graph to better protect your crops.
