Abstract

There are three problems using current GIS software to calculate the horizontal temperature gradient of fishing grid. This work analyzed the errors caused by these problems, and presented a kind of new GIS algorithm of calculating the horizontal temperature gradient of fishing grid, and also presented multisection & single point change surface interpolation method for interpolating grid point temperature based on SST isoline. The results by our algorithms are better than results by ArcGIS.
