Hello R Community, I have imported a dataset which contain X Y coordinates and would like to recreate a shape file after some data analysis. What i have done is to import some taxlot data and join them based on some criteria. I want to check to see how well the joining went by reviewing the results in GIS. A couple things. I cant seem to import a shape file correctly using the maptools

Hi all, I'm faced with a problem applying the sp package: The projection argument in readShapePoly(Shapefile,proj4string="CRS class argument") e.g.: CRS("+proj=aea +lat_1=46 +lat_2=73 +lat_0=60 +lon_0=84 +x_0=0 +y_0=0 +ellps=clrk66 +units=m +no_defs") doesn't have any impact on the plotted object. I also tested the simple example: xy = cbind(x = 2 * runif(100) -

Hi, I want to use map("state") and have the ecoregion shape (please see link) file projected onto this. ftp://ftp.epa.gov/wed/ecoregions/cec_na/NA_CEC_Eco_Level3.zip ftp://ftp.epa.gov/wed/ecoregions/cec_na/NA_CEC_Eco_Level3.zip Could someone please show me how; I have never messed with this sort of thing. Thanks. -- View this message in context:

Hi ALL, Can you please help me on how to determine the prediction error for ordinary kriging?Below are all the commands i used to generate the OK plot: rsa2 <- readShapeSpatial("residentialsa", CRS("+proj=tmerc +lat_0=39.66666666666666 +lon_0=-8.131906111111112 +k=1 +x_0=0 +y_0=0 +ellps=intl +units=m +no_defs")) x2 <- readShapeSpatial("ptna2",

Gracias Beatriz, efectivamente, lo que indicas en tu ejemplo es lo que obtengo al final de mi proceso. En todo caso pruebo tu opción con mis datos, si es como imagino seguro que es más rápida de montar y más elegante que tratar el resultado de un sink() (recuerdo que en su momento lo intenté con fotify pero no supe bien como atacarlo, no conocía el enlace que me mandas, por tanto lo pruebo de

Oscar, al final no he podido esperar hasta mañana Con: library(maptools)library(sp) poligonos <- readShapeLines("C:\\...\\DATOS\\MUNICIPIO.shp") sink("C:\\ ... \\DATOS\\MUNICIPIO.csv") coordinates(poligonos) Consigo un fichero con la suficiente estructura para tratarlo fácilmente y de una tacada montar la tabla .csv tal y como he indicado en un correo anterior Necesito el

Hola buenos días: Hace algún tiempo mandé una duda que sobre fichero tipo shapefile que publica el Instituto Geográfico Nacional de España y que detallo en el word Duda_sobre_shp. El tema es que al final no obtuve respuesta (es cierto que lo mandé en Agosto y en esa fechas entiendo que sea normal, por tanto por recomendación de un conocido vuelvo de nuevo a remitir la cuestión) Como no podía

I imported the attached tiff file and converted the coordinate system to long lat and graphed it: californiatiff<- readGDAL("california1.tif") proj4string(californiatiff) > rasterprojection <- spTransform(californiatiff, CRS("+proj=longlat") however, when using the plot command for rasterprojection, I get a blob. I can see the outline of the state of california and

I have a simple problem: I need to load a ERSI shapefile of US states and check whether or not a set of points are within the boundary of these states. I have the shapefile, I have the coordinates but I'm having a great deal of difficulty bringing the two together. The problem is the various GIS packages for R do not play well with each other. sp, shapefiles, maptools, etc all use different

Hi, I'm trying to plot some data (z) that is linked to lat&long coordinates (x&y). These coordinates are not however on a regular grid. I also have some shapefiles on which I would like to overlay the data. I can plot the shapefiles (country/city outlines) and overplot the data, but only using quilt.plot because I otherwise always get the error message that 'Error in

Hi ! I have a shapefile that I can easily read into R using library(maptools). My problem stems from some warning messages that come even though everything seems to work fine. library(maptools) districts <- read.shape(filen = "a_ds", dbf.data = TRUE) length(districts$Shapes) so far so good. when I try and plot this I get a nice plot and a warning message: > plot(districts)

Hi, I've cross posted with r-sig-debian since they may be an issue for linux (never had this problem on my windows machine...) I recently made the switch to Ubuntu 10.04 (lucid), and found that unionSpatialPolygons() gives me the following error when trying to combine polygons within a shapefile: # Read in shapefile and merge polygons foo <- readShapePoly("foo.shp",

# I am sure that I could be more efficient than this but how? Thanks in advance. #GPS in Decimal Degrees in the form longitude latitude RM215 <- matrix(c(-82.1461363, 33.5959109), nrow=1) SC <- matrix(c(-82.025888, 33.606454), nrow=1) RM202 <- matrix(c(-81.9906723, 33.5027653), nrow=1) RM198 <- matrix(c(-81.926823, 33.4634678), nrow=1) HC <- matrix(c(-81.920505, 33.46192), nrow=1)

Hi, is there a function in R to convert data read with read.shape and which is originally in UTM coordinates into longitude / latitude coordinates? I found the convUL() function from the PBSmapping package but I have no idea how I could apply that to the read.shape object. Many thanks, Werner __________________________________________________ Do sragenden Schutz gegen Massenmails.

Dear all, I'm working with satellite images in R and plotting them via the code below. I was wondering whether coordinates (spatial["x"], spatial["y"]) are used as centre coordinates of the pixels in the GRID? In this script; spatial["x"] & spatial["y"] are the centre coordinates of the satellite image pixels. I'm asking this because some

Dear all, I am trying to create a map for central asian countries(Kazakhstan, Uzbekstan, Kyrgyzstan, Turkmenstan, and Tajikstan). I tried google for shapefiles and Rdata files of central asia, but I can't seem to find them. There is only a world map and individual maps for each countries. If I use individual maps to create this map, how do I put them on a same graphic with different colours?

Dear all, I have been trying to convert coordinates from longitude/latitude to utm but I got an error. As soon as the longitude coordinate is greater than 90, I get the folloowing error message: "error in pj_transform: latitude or longitude exceeded limits" Here is what I did: SP<-SpatialPoints(cbind(126.59,-14.30),proj4string=CRS("+proj=longlat"))

Dear all, in GADM map there are three levels (nation, province and precinct) for each country of the world but for all of them you are never able to plot only one part of a chosen country. To be sure, I am trying to plot only one region of “Italy” and colour the different precincts in it. So far I am able to colour only the part of my interest but the programme still plot the whole country. Is

Hello. I'm new on that forum, so I would use some help... I'm programing with R program, have some exercise to do. So here it goes. 1. I have to upload two libraryes "sp" and "maptools" 2. This command is troubling me : towns <- readShapeSpatial("OB/OB.shp") 3. When I'm pressing f5, there is an error called: Error: could not find function

SUMMARY: Specific problem: I'm regridding biomass-burning emissions from a global/unprojected inventory to a regional projection (LCC over North America). I need to have boundaries for Canada, Mexico, and US (including US states), but also Caribbean and Atlantic nations (notably the Bahamas). I would also like to add Canadian provinces and Mexican states. How to put these together? General
