Which remote sensing satellite is best used for vegetation extent mapping
Hiking & ActivitiesWhich of the satellite are used for land use land cover mapping? Satellite Imaging Corporation (SIC) can provide automated satellite map datasets for vegetation and land cover use by updating your projected area and incorporating a more recent image to determine the changes and update existing Artificial Intelligence (AI) and Machine Learning (ML) algorithms. How
I can not download gpx from GPS through GPS tool with GPS babel on QGIS
Hiking & ActivitiesHow do I import a GPX file into QGIS? -To add GPS waypoints/tracks/routes to QGIS, you will first need to move them to the computer; downloaded with the other files for this practical, a GPX file has been included as an example. Select Layer > Add Vector Layer and select the GPX file type from
Layer failed to load using PyQGIS on macOS Mojave
Hiking & ActivitiesWhat is PyQGIS? PyQGIS is the Python environment inside QGIS with a set of QGIS libraries plus the Python tools with the potential of running other powerful libraries as Pandas, Numpy or Scikit-learn. This tutorial shows the main parts of the Python environment and has some practical cases of vector data layers. What version of
Calculate velocity and errors from distance between GPS points
Hiking & ActivitiesHow do you find velocity with GPS coordinates? First we plot the two GPS points on a spherical model of the earth, then calculate the angle between them using a dot product, then calculate the ‘Great Circle’ distance using this angle and the earth’s radius and finally we divide by the elapsed time to approximate
ArcMap attribute joins generating incorrect values
Hiking & ActivitiesWhy does the attribute table have null or empty values after a join? After performing a join, the values in the fields from the joined table might appear empty or null. Null values can be the result of several factors: Values in the specified fields for the join do not match. Joins are case sensitive,
Calculate new Lat/Lon from initial Lat/Lon plus Cartesian X,Y
Hiking & ActivitiesHow do you convert XY coordinates to latitude and longitude? Calculate latitude and longitude using the formula: latitude = asin (z/R) and longitude = atan2 (y,x). In this formula, we have the values of x, y, z and R from step 2. Asin is arc sin, which is a mathematical function, and atan2 is a
