### Rasterization and Vectorization: Vertices, Paths and Grids

Rasterization converts vectors into rasters. While vectorization transforms rasters in vectors. We explain how to go from one data model to the other.

### Huff Gravity Model: Who Will Visit Your Store?

Huff Gravity Model uses store size and distance along with census tract population to understand the probability that consumers will patron retail stores.

### A Topographic Profile of Arizona’s Massive Meteor Crater

Topographic profiles are cross-sectional views showing elevation along a line with applications in engineering, hydrology, land use planning and more.

### Why Are Great Circles the Shortest Flight Path?

Airplanes travel along the true shortest route in a 3-dimensional space. This curved route is called a geodesic or great circle route.

### How Aspect Creates Microclimates for South-Facing Slopes

In the mountains, the terrain slopes are in all directions – east, west, north and south-facing. The compass direction that the slope faces is slope aspect.

### How To Vectorize Image Files Automatically with ArcScan

You can take any image, and you can vectorize it with ArcScan. This means you’ll spend less time digitizing and more time doing other important things.

### Inverse Distance Weighting (IDW) Interpolation

Inverse Distance Weighting (IDW) interpolation estimates unknown values with specifying search distance, closest points, power setting & barriers.

### Pick Optimal Business Space with Location-Allocation

Tech-savvy companies are using the location-allocation tool to find optimal location and target market. Here’s an ArcGIS solution to locate your company.

### Flow Direction Calculates Water Direction Using Slope

Flow directionÂ calculates the direction water will flow in its eight adjacent cells using slope from neighboring cells (in a raster grid cell)

### DEM, DSM & DTM Differences – A Look at Elevation Models in GIS

We explore the differences between DEM (bare earth), DSM (natural and built environment) and DTM (vector contours and regularly-spaced points).
