Bands 3 and 4 are used tocalculate NDVI. For more information on how to calculate NDVI from Landsat 7 imagery, see the link attached (Calculating NDVI in ArcGIS using Landsat 7 satellite image – YouTube). From
Zonal Statistics uses groupings to calculate statistics within specified zones. For example, you can calculate everything from mean, median, sum, minimum, maximum, or range in each zone. The zonal extent could include anything from country boundaries, watershed catchment areas, or property parcels ...
How to Use ArcGIS Pro to Determine the Population Impacted by Air Pollution How to use ArcGIS Pro and Landsat 8 Imagery to Calculate Chlorophyll Index and Global Environmental Monitoring Index How to Use ArcGIS Pro to Estimate Soil Erosion from a Catchment Basin...
If you want to identify which locations fall within a travel time catchment area, and which lie outside this requires a slightly different process. Follow the tutorial below to filter your points and calculate the distance to each. Try our free point in polygon tutorial How can I use the Tr...

Therefore, a comprehensive inventory analysis of major elements (cations and anions) in farmland soil should be conducted to calculate the acid production rates by nutrient inputs, as well as the corresponding buffering provided by base cation release and probable anion adsorption (Zhu et al., ...
Next, find the TravelTime_platform toolbox in the Catalog window and double-click the Time Map Simple tool: Figure 3: The Time Map Simple tool in the TravelTime toolbox Use the following settings to calculate the catchment areas for all three address locations and click “Run”. The three...
It has obvious advantages in the quantitative analysis of the spatial agglomeration characteristics of points in the whole region. Therefore, kernel density analysis was used to calculate the density of spatial point and line elements within the neighborhood around the station to simulate the continuity...
(SWAT) model) to simulate water yield, the Carnegie-Ames-Stanford Approach (CASA) model to estimate Net Primary Productivity (NPP), the Universal Soil Loss Equation (USLE) model to calculate soil erosion and the Crop Productivity (CP) model to simulate agricultural productivity to quantify the ...
