I'm fining out the ways to achieve Post processing dgps.
I use android phone as the gps receiver.
Now, I've generated the GPX or KML files using an android app gps logger. I need to convert this into Rinex format in order to do post processing. I cudnt find any converter tool for this while searching the net.
Is there any other way to achieve this?
The "easiest" way would be to use XSLT since the gpx and kml files are both xml.
Impossible. RINEX requires more details than GPX.

For a beginner, how do I model simple data nodes and relationships using A-frame. I'd like to create a rudimentary VR visualization? Can I upload a file, what format would it be, what else do I need to do? Thanks for any help to get started or links!
Some people in the d3.js (data visualization library) community have been playing using it with A-Frame. There are lots of examples on http://blockbuilder.org/search#text=aframe . JavaScript and d3.js can take and load any file format to be parsed, most common is JSON and CSV.
I also have a visualization using d3.js + A-Frame at https://ngokevin.github.io/kframe/scenes/statistics-dashboard/ for calendar heatmap.
Ben Pyrik has some components as well, such as for scatterplots: https://github.com/bryik/aframe-scatter-component
I'm downloading and saving audio files from a URL. I'm trying to ensure that I'm properly implementing my variables and am storing the files themselves properly.
Is there an ideal or standard way of declaring variables to receive audio data or storing these downloaded files? I'm planning on just using NSURLRequest and NSURLConnection to download and save the files to the file system. Maybe reference them using CoreData. Is this a fairly standard way of going about this, or should I change my approach?
I don't believe there is anything special that you need to do for downloading audio files. I have myself downloaded and saved video and PDF files before, both in the same and usual way and didn't have any issues.
For reference you can check this question out: How to download audio/video files from internet and store in iPhone app? It has a very nice detailed answer.
Hope this helps.
I need to capture video from the webcam and save to file(mp4 format). what is best way to do this using C#.net 4.0 application?
Are there any solutions which doesn't involve WIA(Windows Image Acquisition) / DirectShow? Or do i need to use either one of them?
I know a third party toolkit named leadtools that might help you. This toolkit uses the DirectShow's filters and codecs to capture videos from webcams. Also, it provides easy ways manipulate the captured videos and save them with many formats including the MP4. For more information, you can check this Tutorial
I have a requirement to take idml files provided by a client, twiddle them a bit to fill in some placeholders and generate a TIFF file. This needs to happen automatically and I have InDesign Server at my disposal.
I have the first part down. I have also found how to connect to InDesign Server via SOAP and convert IDML files to hi-res PDF or low-res JPG (This implies a few other other options).
I am at a bit of a loss as to how to take it the rest of the way to generate a TIFF file, the adobe forums have not been much help. It is my impression that this sort of thing is exactly why the IDML format was introduced so I'm assuming there's decent support out there for it but the best I've been able to come up with so far is to go IDML via Indesign Server to PDF (or SVG) via Inkscape Command-line to PNG via System.Drawing to TIFF but that seems horribly contrived and fault-prone (and I have no idea how I'm going to handle multiple pages).
Any ideas?
I don't believe there is a way to export to TIFF via InDesign Server, however I did find this post on the Adobe Forums that suggests using Photoshop to render the Tiff after exporting it as a PDF from IDS. Maybe that would be an option? Otherwise maybe you could use one of the formats that you CAN export from (i.e. JPG, PDF, EPS).
Hope this helps!
For reference, I ended up using Ghostscript to achieve the results.
I'm looking to do a little iOS app that uses has some very basic YouTube interaction. When I say basic, I really mean it: All it needs to do it pull in the uploads from a particular user, the videos' links, titles and maybe a thumbnail.
I've been looking at the Google developer docs for YouTube and nothing seems to be of help. It seems that the data is stored in an XML format, but it seems completely different to the structure of the sample XML in the docs. I don't know whether I'm using the wrong link (this is a sample of what I'm looking at now), but I just get a really messy XML document.
I've really no idea where to start on this one (with regards to a parser) - it just looks so messy. If someone could point me in the right direction with this, maybe even a with some sample code on a parser, I'd be incredibly grateful.
Thanks,
K
Have you considered making use of gdata-objectivec-client api http://code.google.com/p/gdata-objectivec-client/ It comes with samples which provide exactly what you are looking for.
Here's a very concise and easy-to-read example using NSXMLParser. It provides an example xml and shows you how to parse its elements and populate a custom object with the values.
i can suggest you to use LIBXML 2.2 it's easy to use and you can use Xpath Query to fetch whatever you want from any messy file.
To learn how to use that look at this page. link
The XML link you provided looks like the atom feed. If you don't feel like parsing the XML in your code, you can try the TouchRSS (https://github.com/TouchCode/TouchRSS) which I used to parse the youtube RSS feed. The RSS feed version should be in version 2 so the url you provide should change to http://gdata.youtube.com/feeds/base/users/DJ3Lau/uploads?orderby=updated&alt=rss&v=2.
