Re: [R-sig-Geo] Using the Z value for 3-D polygons?

Jim, I'm sorry that this not answer your question; refering to this graphic gallery, I discovered that fig21 is no longer matches current states in sp, so I updated the complete set on sourceforge (and the sources in cvs, target spweb). For fig21, I also had to update the generating code, as panel

[R-sig-Geo] Using the Z value for 3-D polygons?

Hi Everyone, QUESTION: How can I plot a spatial polygon (SpatialPolygonsDataFrame) as 3-d? Perhaps using "spplot.polygons" with its z value? GOAL: To have a series of polygons look like approximately like the last example in the PDF below. http://ocw.mit.edu/NR/rdonlyres/Urban-Studies-and-Pl

Re: [R-sig-Geo] testing DEM geoprocessing in RSAGA, SAGA GIS and ARCGIS: different of results in value range

It seems that SAGA GIS stores angles (slope, aspect) in internally radian, but it shows them in degrees when displaying them in the GUI of SAGA GIS. I noticed that once in the context of slope angles and was pretty puzzled... just do *180/pi to convert radian into degree. A. gianni lavared

[R-sig-Geo] testing DEM geoprocessing in RSAGA, SAGA GIS and ARCGIS: different of results in value range

Dear Professor, Thanks for your competence and your work in RSAGA and Rypgeo. This packages are very useful and interesting. I am testing different geoprocessing code in RSAGA, SAGA, Phyton and Rypgeo to see the results, but I noticed a singular situation. I am using this code to create SLOPE and

Re: [R-sig-Geo] HELP with RPyGeo and RSAGA slope function

Dear Gianni, ArcGIS is not that flexible; it does not allow you to directly create an ASCII raster as an output of a geoprocessing tool. Try this to create an ESRI raster "SLOPE" and then convert the result to ASCII: setwd("C:/work") env = rpygeo.build.env(overwriteoutput = 1, work

[R-sig-Geo] Help with RPyGeo and RSAGA to SLOPE code

Hi All, I am using Alexander Brenning RPyGeo. I have a DEM.asc (ASCII File format) and I wish to obtaion SLOPE (possible always in ascii formta) in percent. But I have this problem: rpygeo.Slope.sa ("C:/work/DEM.asc","C:/work/SLOPE.asc",unit=c("PERCENT_RISE"), z.factor =
