Is it possible to open a MrSID file using the raster or rgdal packages? Specifically I'm looking for something of the form raster(myraster.sid).

How can I convert the file I uploaded to Forge to svf format and then download it to my own server?
I wanted to do these operations using your project "https://github.com/Autodesk-Forge/forge-bucketsmanager-desktop/tree/master/bucket.manager". As a result, I downloaded it, but there are files in it that I will not use. The reason for this is that the load on the download process increases. I just want the "3d views" folder. Can you help with this?
As Alex said, the structure of an SVF asset can vary depending on the input file format. For more details on how to download the SVF (or just some of its parts), take a look at the forge-convert-utils library, specifically the SvfDownloader. It parses the actual SVF file to identify all the additional assets (e.g., geometry files, textures, property database files, etc.) that need to be downloaded as well.
The format of the map imported should be preferably ".shp" file.Also please tell how to create such a file. I have tried KML but it didn't work.
Yes, vectors need to be .shp to be imported. You can create vector files in most GIS programs (ArcGIS, QGIS, etc) and export to .shp. Or there's online tools for converting KML to .shp (eg http://www.zonums.com/online/kml2shp.php)
Raster files need to be saved as .ASC or .GRD for use as a dataset in Netlogo.
I would like to use the parallel coordinate toolkit from syntagmatic.github.io/parallel-coordinates/#.
As I am new to the D3.js framework, I am encountering some trouble to begin and visualize data locally.
What I am trying to achieve is to use one of the standalone HTML examples (e.g. brushing.html) and edit the data table with my own data.
I stored locally (in a Windows folder):
the brushing.html example file
the cars.csv file
the D3.js library files from d3js.org (d3.min.js and d3.js)
When I load the HTML file in my browser, only the text displays, not the parallel coordinates themselves.
What am I missing/doing wrong? Should I be able to display locally the same result as what appears in brushing.html?
I checked out several tutorials for D3.js, but they generaly skip these preliminary requirements step. Thanks for any feedback.
Thanks to the straightforward comment to my question, I was able to identify the issues checking the browser's console.
It mainly came down to redefining paths to the different files, and eventually downloading the missing packages from the corresponding Github page https://github.com/syntagmatic/parallel-coordinates
I can now test the tool locally with custom data.
First of all: I'm a skilled developer and a total noob of 3D solid files/drawing.
I started playing with webgl and three.js. My task is to port a solid 3D file(i.e. STEP/IGES) to a web page(a sort of a cad viewer).
I started from this example:
http://www.johannes-raida.de/jnetcad/RadialEngine.htm
I want to obtain something like the above link with
a navigation tree and hide/show layers functionality.
The above link has sever json file, one for layer.
I want to obtain: a threejs-json file for each layer to get the hide/show functionality.
Now, I have a solid file (STEP format: .STP). That file contains layers. I want to obtain a json(three.js) file for each layer.
Questions are:
how to export to threejs-json using free software? I read that the best method could be: STEP > Wavefront OBJ [using freecad?] > treejs-json [using blender?]
Does the collada format is better than obj?
Shoud I have to manually export each single layer to json?
Is there an utility out there to generate all the layers(separated files)(json-threejs format) from a 3d file?
So, I did it by myself.
Three.js is a great library but it requires some 3d skills.
Here are my answers:
how to export to threejs-json using free software?
Well, my suggestion is to convert your solid file to DAE, use anything you want.
Then open DAE with Blender and use the exporter script of three.js:
https://github.com/mrdoob/three.js/tree/master/utils/exporters/blender
Shoud I have to manually export each single layer to json?
No, the 3D file has all the informations about layers. So you can use a single file.
Is there an utility out there to generate all the layers?
I don't have found somethig good out there.
If you want to create single layers, you can split the json file created with blender.
Thanks for the assist on my previous question.... I was able to complete my project
This time I have a CAD file created with Autodesk that I need to convert to a shape file.
Couple of questons:
An open source application (can't afford ESRI) that can convert the CAD file to a shape file?
Is that a better file format I can use other than the shape file (shp) format?
Any suggestions would be greatly appricated

Chris
I would also suggest to use OGR but in only works with dwg/dxf version 2000 or prior; you could use Teigha (http://www.opendesign.com/) to convert the files to 2000 version and then you can use OGR.
I've done tons of conversions from dwg to shp what I usualy do is convert the dwg to a dwg version 2000 using Teigha, then convert that dwg-200 to a shape file; once a shapefile you'll see that this file contains all the layer in order to separate each layer into a different shape file I use this command
ogr2ogr new_map_from_layer_X.shp -where "LAYER = 'X'" shape_converted_from_DWG_lines.shp
You should use OGR

It is the main program for converting between geographic formats. It is written in C++ but there are also python bindings. It is compiled and runs on almost every major OS.
