I want to create wayfinder/pathfinder mobile application. it will route visitors in our buildings. we have 20 buildings and each at least have 4 floor.
We want to develop our own wayfinder ex:http://www.wayfinderkiosk.com/
It should use Lat/Long coordinates to locate the people. and help to find its route.
So where should i start. Does any one have any idea for that. and it is going to be mobile.
I can develop app/site based on these platforms ( Mobile Web/Iphone/Adroid /Symbian/Windows )
But i need a start point. and i need your help.
Thanks
You want to use lat/long inside of a building? Assuming these visitors are going to be using their own unmodified devices, you may have trouble with GPS. Unless you somehow get reliable GPS signal despite being under a four-story building, that's probably not going to work.
An RFID-tagged badge and sensors placed throughout the building seems more likely to work. Put a unique QR-code on each badge that directs the phone's browser to a tracking page for that specific badge.
edit: and now that I re-read your question and see that multiple buildings are involved, the GPS bit could certainly work for routing them from one building to another.

This is my first time getting into drones.
I am looking at DJI drones, currently as it seems most promising from a documentation and reviews point of view.
Basically, I would like to program a drone(s) to fly a certain pattern and take pictures when a certain criteria is met. For example, I would like the drone to take off and fly around a small park, stopping to take a picture of each tree it encounters, automatically (auto-piloted / driven by some "AI").
Now I glanced thru the DJI SDK documentation, and so far it SEEMS this is possible (via FlightControl class). But im not sure.
Question:
Can my requirements be met with current drone SDK technologies?
Yes, the correct SDK, 4.11.1 will do everything you mentioned. You will need to do some location calculations but that's about it.
The sample will almost do everything you want as-is, with minor changes.
With the DJI Mobile SDK you can use the Mission classes to automatically fly a given set of coordinates (waypoints) and do some actions once you arrive at a waypoint, e.g. take a picture.
However the SDK has limitations:
The SDK is unable to detects objects in the video stream. Therefore it is needed to use your own code to detect objects yourself.
The way the drone flies to the waypoint is quite limited, e.g. the drone will always face the camera in the direction of flight.
When using the DJI Mission classes, a change of the route during execution is only possible with the use of timeline Missions by adding timeline elements to the list.
As you already assumed in the comment: Yes, the Mobile SDK is more advanced than Windows SDK.
I am planning to develop a hybrid mobile app using ionic. One of the features i need is offline google map. Is there a way how to do it?
It depends on the requirements of your application whether this will be possible. Are your users on "modern" devices A.K.A is HTML5 fully supported? Do your users need to view/edit the map globally, or just in a specific area? Does the map really need to be provided by google? I'll address some issues below to point you in possible takes on this problem.
Do you really need google maps? (Most optimal scenerio)
First of, do you really need google maps? Also relevant: how far do your users need to zoom their maps? If it can be any maps, and zooming is not really of high priority (if it is, including all map tiles will make the app eat all storage), you could probably use map-tiles as a packaged part of your app, and display them with a library like http://leafletjs.com/. The library is well documented, and provides a map-interface for a variety of map-providers. It will be do-able to configure this to use your own local map-tiles. You could include map-tiles for multiple zoom levels if necessary, and limit the min/max zoom-levels to the tiles you actually have available. This will make your maps work offline.
I can't or don't wan't to provide my own tiles make sure that you really looked into the option, there is systems out there that provide map-tiles you could use (check https://www.mapbox.com/ for example)
Okay, so you really don't want to do what I suggested. What are the options now? Javascript mapping-solutions typically render tiles based on the location of the map you want to see and the zooming level. These tiles are requested to the tile-provider. I do not know how to implement this for google exactly, you might need some research on this - I'll try to help you see a direction. There will be requests to get the tiles from the servers. I checked with http://maps.google.com what images are loaded when trying to navigate the map: (example (click)). Find out what url's are used in your situation, we will need these kind of url's later (just inspect the network tab in your browser console and see which requests are made when scrolling in your map). When we only need our users to work in a certain area when offline we could use service workers to cache the responses of these requests when we are online, and serve those caches when we are offline. Read more on service workers here (click).
Advantage: Real offline map-functionality for any tile you visited before (as long as your cache wasn't overflown, depending on your implementation of the service workers, and for service-worker supported browsers/devices).
Disadvantages: No support for tiles that were never put in the cache (AKA: never seen before). Another one: this will only work for devices that support service workers. Might be an option in situations where you either don't care about users using "older" devices, or where you can control the user's device choices. Note that using crosswalk could ease your developing efforts here, since you only have to consider one browser-runtime then: but crosswalk also doesn't support older devices.
However: This solution could be fine for people that will need to work in a specific area, which might be true for the case provided by #vipul-r If you or your users know in advance where they need their maps to work, you can instruct/help them in loading & caching their maps correctly.
If you can't work on either of these 2 solutions, then I highly doubt there will be a way to do it. I don't see any other way to the best of my knowledge.
I want to push card into my app in the Google Glass, and not to the timeline, my app in the glass contains cards with names of friends, I want to give ability to each one of the friends sending card under the friend name.
I will be happy to know if this behavior allowed, Thanks.
It depends exactly what you mean. In general, it is best not to think about specific apps when it comes to Glass, but rather to think about actions that take place using Glass. So instead of "starting" an app that shows the names of each person, we might instead think about wanting to send a note to that person and have that person be on our contact list to get a note if we wish to send them one.
Doing it this way, your Glassware needs to create and maintain contacts and register them with the TAKE_A_NOTE action. See https://developers.google.com/glass/v1/reference/contacts for more details.
It isn't clear what you are trying to do exactly, but it sounds like you might be able to use card bundles as well. Take a look at https://developers.google.com/glass/develop/mirror/static-cards#bundling_cards to see if this scheme will work for you.
If you're not doing it either of these ways - you may need to update your initial question to clarify how you are starting and running the app itself and how you picture the entire workflow.
I've been asked to create a stand-alone site/app that's not connected to the web (all on a local server).
One part of it is to have a map of a natural reserve with a bunch of links that will show footpaths, different animals habitat areas, visitor centres and such.
So there's a map (static picture) and when you click on it some overlay goes on top of it.
At least that's the way I see it now.
I've looked here: http://www.carto.net/williams/yosemite/ but it just looks mucho ugly.
Getting Maps Premium is not an option as it's not that cheap. And the reason they don't want to use Maps/Earth free API is because internet connection is still very slow there (sattelite internet only and when optic cable will be hooked up nobody knows).
Looking for some recommendations as to how to proceed there. Drawing paths/areas on the picture of the maps seems extremely insufficient and time consuming.
I'd need some way to use coordinates to automatically draw areas and lines over the map (and then somehow export that as a graphis file (or SVG) that'll be layered on top of original map simply using ajax.
Will ARCGIS pro edition be the way to go or should I start learning SVG. Do you know some good SVG books/tutorials (as related to mapping)? Maybe there's some other way around altogether...
They do have detailed maps of the area in ARCGIS (whatever format they are in I don't know yet).
Just looking for some ideas, any help will be appreciated. Thanks in advance.
Do you know GeoServer? More or less all-in-one, compatible with different types of datasets, widely customisable.
Starting from "raw" SVG and write the whole thing yourself will probably be prohibitively time consuming.
If you have very little data (say less than 50 geometries) that is fixed, you could also use OpenLayers without any backend server.
For the data you could use a OpenLayers.Layer.Image if your (overlay-) map consists of a small raster image. For vector data, you can use OpenLayers.Layer.Text or a OpenLayers.Layer.Vecor together with protocols OpenLayers.Layer.KML or .JSON.
You can click through the current release examples.
I admit that this is not an easy task for a beginner, but it's fun hacking the maps together.
We are getting ready for a trade show early next month where we will not have Internet access on the show floor. We've put together machines with local installations of apache, mysql, etc. and are using host files to mimic the various domains we access.
But, one feature of our software is using Google maps to get directions from one address in the system to another. In order to show this, I need to be able to spoof a map or two.
I don't need to zoom in or do anything with the map image for the show. Just need to show the rendered map page with the directions list, etc.
I'm not having any luck with browser extensions to capture the entire page to an image. They either crash, or don't get the part of the map below the scroll.
Does anybody have any thoughts on how to get this rigged up for the show - either programatically or using tools that you've tried and found to work?
Amy
just do a screen capture of the whole page
edit: saw the part about not having luck with browser extensions. On a PC, you can try SnagIt, which has a scroll-and-capture functionality. Or, just do it manually and stitch together in photoshop. It can't be that long of a page....
