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...
By plotting the two maps together in ArcGIS we could calculate the areal exposure for each different Methods Three big (5 kg) sand samples were collected on active sand bars in the final tract of the Lhasa (Kyi) River (sample 16A002; GPS coordinates: N29.374250, E90.859500) and of the ...
I used the Pythagorean theorem to calculate distance from each customer point to branches, and then did a formula to identify which branch the household is closest to and if it's within + or - 0.5 Lat AND Long. My main issue with doing it this way is the Pythagorean theorem is based o...
81.Exclusive Economic Zones– Carving out boundaries in the Arctic – Canada, Norway, Russia, Denmark (via Greenland), and the United States are limited to their economic adjacent to their coasts while all waters beyond are considered international water. 82.Shipping Route Shortcuts– Transporting ...
I am currently trying to plot sales branches on a map and then show an area around each point (I have generated longitude and latitude for most but not all branches, so in this case I may use zip code since I have ...
Multiple linear regression was used to calculate predicted NDVI values influenced only by climatic factors, with temperature and precipitation—the two main climatic factors affecting vegetation-cover change—being used as independent variables [68,69]. The equations are as follows: 𝑁𝐷𝑉𝐼𝑐...
Therefore, this model is used to calculate FVC in this study, and the formula is shown in Equation (1). FVC=(NDVI−NDVIsoil)NDVIveg−NDVIsoilFVC=(NDVI-NDVIsoil)NDVIveg-NDVIsoil (1) where NDVIsoilNDVIsoil is the NDVI value for the non-vegetated area; NDVIvegNDVIveg is the NDVI...
ignoring changes in residential communities accessibility. This research provides new ideas to evaluate PGS. Based on parks and residential communities’ data, we adopt an improved Gaussian-based two-step floating catchment area (2SFCA) method to evaluate PGS accessibility in Ningbo (China) and its ...
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...
A multi-step procedure was implemented utilizing NCEL Radar Software, ArcGIS 10.7, and the standard UNIX Command. The decoding step produced about 2700 radar images for the selected events. Precipitation grids are required to be in the Data Storage System format (HEC-DSS) for use in the HEC-...
