Farm Colormap Data Through Satellite

Satellite data regarding vegetation relies on actual observations. For instance, when monitoring cultivated land, the satellite captures images of the exposed soil, which are then utilized to generate satellite images. Additionally, the height of vegetation is crucial for assessing crop health and condition. Analyzing such data often involves color coding or specialized analysis techniques. Accurate interpretation of crop health data aids farmers in optimizing farm management practices.

Challanges

During the early stages of vegetation, the soil is more prominently visible to satellites, resulting in indices derived from default analysis scales. Conversely, taller vegetation provides more accurate data images.

At the early stages of vegetation growth, issues may not be readily identifiable, complicating decision-making processes. To address this, Precision Grow has introduced two types of colormap.

About Colourmap:

Colormaps facilitate the assessment of vegetation conditions during early growth stages. These come in two varieties:

• Colormap 1: Ranging from 0.1 to 1, this default colormap initially displays all indices. It utilizes a color spectrum from green to red, indicating good vegetation in green and danger in red.

• Colormap 2: Spanning from -1 to 1, this colormap is specifically designed for early growth stages or shorter vegetation. It employs various shades of green. Colormap 2 is recommended for early growth stages.

Colormap 2 provides insight into crop accuracy and sensitivity. It essentially magnifies the range of 0.1 to 0.2 from colormap 1, representing it in different shades of green. Even when an entire field is sown on a particular day, growth issues in specific areas may not be apparent with colormap 1, necessitating the use of colormap 2. These colormaps are applicable to indices such as NDVI, NDRE, NDMI, NDWI, SAVI, EVI, VARI, and RVI, but not to TCI, ETCI, hybrid images, DEM, and colorblind visualizations.

How to Access Colourmap?

• Step 1 : Log in to your Precision Grow account.
• Step 2 : Select the field recently sown or in an early growth stage.
• Step 3 : Choose the desired image, such as NDVI.
• Step 4 : Opt for either colormap 1 or 2 based on the vegetation.
• Step 5 : Analyze the displayed image according to the scale.
