projection

I am trying to change or assign the projection of a Germany-Shapefile from NA to +proj=longlat +datum=WGS84 +no_defs +ellps=WGS84 +towgs84=0,0,0 , but somehow it doesn't work well. Reproducible Example: Shapefile and other files can be downloaded here : What I tried is the following: library(maptools) library(sp) library(rgeos) library(rgdal) projection.x <- CRS("+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs +towgs84=0,0,0") mapG <- readShapePoly("vg2500_lan.shp", verbose=TRUE, proj4string=projection.x) summary(mapG) mapG <- spTransform(mapG, CRS("+proj=longlat +ellps=WGS84 +datum=WGS84"))

Is something like this possible? I want to pass an "hasfocus" variable from cjc-box through ng-content attributes to the cjc-input component. app.component.html <div cjc-box><div cjc-input></div></div> cic-box.component.html <div class="cjc-box"> <div><ng-content hasfocus="focus"></ng-content></div> </div> cic-input.component.html <input class="cjc-input" type="text" focus="{{hasfocus}}" /> Is this even possible with projections in ng2? It is possible to pass variable to projected content (assuming component cjc-box declares property focus and component cjc-input declares property hasfocus ):

Given a picture taken by a simple digital that contains an image of a rectangle of known dimensions. How can I - to some degree of accuracy - determine the parameters of this camera? I am mostly interested in Pan-, Tilt- and Swing angles. Optionally distance to the rectangle would be nice. I acknowledge the fact that the focal length and resolution of the camera should be known, but it can be assumed that they are available (for example through exif metadata). Are there any simple algorithms for this problems? What you are looking for are camera calibration algorithms. A commonly used one is

I have a shapefile of world countries, downloaded from here . I can plot it in R using countries <- readOGR("shp","TM_WORLD_BORDERS-0.3",encoding="UTF-8",stringsAsFactors=F) par(mar=c(0,0,0,0),bg=rgb(0.3,0.4,1)) plot(countries,col=rgb(1,0.8,0.4)) Now I wanna plot it in orthographic projection (Earth seen from outer space), so I'm trying countries <- spTransform(countries,CRS("+proj=ortho +lat_0=-10 +lon_0=-60")) I also played with the x_0 and y_0 parameters (as stated here ), but I always get the error: non finite transformation detected: [1] 45.08332 39.76804 Inf Inf Erro em .spTransform

I want to create a oblique (cavalier) projection in OpenGL. I know this operation is not default supported and instead I need a Shear Matrix and then make an Orthogonal Projection. Can you tell me what are the OpenGl steps / functions that I have to make? I've not used a oblique/cavalier projection before, but the following should give you an idea of how to proceed: Create a 4x4 shear matrix, H(θ, Φ) = | 1, 0, -cot(θ), 0 | | 0, 1, -cot(Φ), 0 | | 0, 0, 1, 0 | | 0, 0, 0, 1 | θ being the shear in X, Φ being the shear in Y, and Z being left alone.

I have an IQueryable whose Entity Framework 4 objects I would like to project to their DTO equivalents. One such object 'Person' is an EF4 class, and the corresponding POCO PersonP is a class I've defined. I am using Automapper to map between them. However, when I try the following code: IQueryable<Person> originalModel = _repo.QueryAll(); IQueryable<PersonP> projection = originalModel.Select(e => Mapper.Map<Person, PersonP>(e)); The projection generates this error at runtime: LINQ to Entities does not recognize the method 'TestSite.Models.PersonP Map[Person,PersonP](TestSite.DataLayer.Model

UPDATE: I found that, http://os.ivrpa.org/panosalado/wiki , has an implementation in java. Anyone who has something similar in c or c++? I have this panorama, an spherical map from google streetview, and want to map this on a sphere/cube. Below are some examples and illustrations, what i seek is a library that can do it, or some implementation guides. I tried http://krpano.com/docu/tutorials/quickstart/#top that gives the results listed at the bottom. It illustrates what i want, but the rotation axis is off. I need to create the views of direct ahead and back, left and right. Ideal i would
