Abstract: In some embodiments, scripts may be used to perform parcel data acquisition, conversion, and clean-up/repair in an automated manner and/or through graphical user interfaces. The scripts may be used, for example, to repair geometries of new parcel data, convert multi-part parcel geometries to single part parcel geometries (explode), eliminate duplicate parcel geometries, append columns, create feature classes, and append feature classes. These scripts may be executed in a predetermined manner to increase efficiency. In some embodiments, different combinations of attributes may be appended to stored parcel data. In some embodiments, a tracking application may be used to track information about sources of data. In some embodiments, a tracking application may be used to track which system users are assigned to specific tasks (e.g., in a data acquisition project).

Abstract: Method of assessing population with a spatially-stratified random sample comprising creating a grid on a study area, the grid being defined by target grid points to form grid cell, dividing each grid cell into a series of sub-grid cells, each of the series of sub-grid cells being identified from left to right and bottom to top within each of the grid cells, identifying and listing each sub-grid cell that intersects the study area, the list of sub-grid cells being sequences in the same order as the grid cells and the sub-grid cells, dividing the sub-grid list into sections, each of the sections being configured to have substantially equal numbers of sub-grid cells, and the number of sections being equal to the number of targeted grid points, and selecting a random sub-grid cell from each section of sub-grid cells to obtain the spatially-stratified random sample.
