I have downloaded India.osm file. I have a windows application written in C#.net. I would like to use GMap.net to plot routes/pin heads etc using offline data from India.osm file. But I do not have any information on how to use GMap.net with .osm files. Please advice.
You need parse osm file and add routes/points/etc to the map

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.
I was downloading Revit models from BIM360 team hub via ForgeAPI using the following uri.
https://developer.api.autodesk.com/oss/v2/buckets/:bucketKey/objects/:objectName
All my objectName ended with .rvt. So I downloaded and saved them as rvt file.
However I noticed that some of the files cannot be opened by Revit. They are actually not rvt files but zip files. So I have to change the extension to .zip and unzip the file to get real 'rvt` files.
My Problem is that not all files is zip file. I cannot tell from the API because the URI I request is always ended with .rvt.
Every Unix OS provides the file command, a standard utility program for recognising the type of data contained in a computer file:
https://en.wikipedia.org/wiki/File_(command)
A zip file is directly recognised and reported like this:
$ file test_dataset.zip
test_dataset.zip: Zip archive data, at least v2.0 to extract
A Revit RVT model is a Windows compound document file, so it generates the following output:
$ file little_house_2021.rvt
little_house_2021.rvt: Composite Document File V2 Document, Cannot read section info
Hence you can use the same algorithm as file does to distinguish between RVT and ZIP files.
Afaik, file just looks at the first couple of bytes in the given file.
The Python programming language offers similar utilities; try an Internet search
for distinguish file type python; the first hits explain
How to check type of files without extensions in Python
and point to the filetype Python project.
Other programming languages can provide similar functionality.
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.
Im trying out the MarkLogic Java API and would want to bulk upload some files with the extension .csv
I'm not sure what to use, since the Java API only supports JSON, XML, and TXT files.
How do I batch upload files using the MarkLogic Java api? Do i convert everything to JSON?
Do i convert everything to JSON?
Yes, that is a common way to do it.
If you would like additional examples of how you can wrangle CSV with the Java Client API, check out OpenCSVBatcherExample and JacksonDatabindTest.testDatabindingThirdPartyPojoWithMixinAnnotations. The first demonstrates converting the csv to XML and using a custom REST extension. The second example (well, unit test...) demonstrates converting the csv to JSON and using the batch upload (Bulk Writes) capabilities Justin linked to.
If you have CSV files on your filesystem, I’d start with mlcp, as suggested above. It will handle all of the parsing and splitting into multiple transactions/batches for you. Take a look at the mlcp documentation for more details and some example configurations.
If you’d like more control over the parsing and splitting logic than mlcp gives you out-of-the-box or you’re getting CSV from some other source (i.e. not files on the filesystem), you can use the Java Client API. The Java Client API allows you to efficiently write batches using a WriteSet. Take a look at the “Bulk Writes” example.
According to your reply to Justin, you cannot use MLCP because it is command line and you need to integrate it into a web portal.
Well, MLCP is released as open cource software under the Apache2 licence. So if you are happy with this licence, then you have the source to integrate.
But what I see as your main problem statement is more specific:
How can I create miltiple XML OR JSON documents from a CSV file [allowing the use of the java API to then upload them as documents in MarkLogic]
With that specific problem statement:
1) have a look at SplitDelimitedTextReader.java from the mlcp source
2) try some java libraries for this purpose such as http://jsefa.sourceforge.net/quick-tutorial.html
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
Regards
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.
