Spatial mapping of plant traits and canonical variates predicted from regression models was completed using the grid algebra function (raster calculator) of the arcgis 9.3 Spatial Analyst extension (ESRI, Redlands, CA, USA).
In Filiberta Sachanski's first-grade class at Hillcrest Elementary School in the Elgin district recently, a projected image read "Llevar las cuentas con la calculadora" ("Solve the problems with the calculator") as students learned about subtraction using a grid of numbers from 1 to 50 — the "calculator".
To calculate the sediment thickness, the raster calculator was used to subtract the base sediment surface from the Digital Terrain Model (OS Open 50 which was recalculated to a 1 km grid spacing for this study).
Using the raster calculator tool in Spatial Analyst, we created natural log-transformed grids for distance variables, as well as grids depicting a quadratic form for terrain and vegetation variables.
Using the raster calculator, a conditional statement was used to generate a new grid which showed the maximum depth of the combined surfaces considered to be above the basement, therefore the new grid generated represented the base of sedimentary rocks or top of the basement rocks, but not including areas where basement rocks were at surface/outcrop.
This calculator has a larger LCD panel to graph results on a coordinate grid.
If you are using your unit in the horse latitudes (see map, pp. 202-223), it cannot be switched from Marine Haircut mode to Calculator mode without a Supplementary BatteryPak or plug-in access to a power grid.
We converted the floating-point output models of Maxent into integer grids (retaining first 3 decimals), which are easier to manipulate in a GIS-framework, using the Raster Calculator in ArcMap 9.3.
Out popped his calculator.
