I'm new to geospatial indexing and found H3 to be really interesting. Currently messing around with the several different functions on API, but my question is how do I render the H3 cells to a map?
What map do you suggest, and how do I go about it?
Kind regards,
Mo
The answer depends partly on what version of H3 you're using - JS, Python, Java, etc. In general, the easiest way to render H3 cells is to use h3ToGeoBoundary to get each cell as a polygon, then encode this as GeoJSON or a similar standard format and load that in your map (which could be a web map like Leaflet or MapboxGL, or an application like QGIS, or some other rendering library).
You can see rendering approaches using MapboxGL in the H3 tutorials on Observable
In Javascript, you can use the geojson2h3 library to more easily convert between H3 and GeoJSON

I want to implement a map like this:-
in which vector layers of countries are highlighted according to some metric value. I tried to search for some package but found JQuery based JQVMaps and jvectormap, which I want to avoid to use since my framework is VueJS.
Can someone suggest some package for this? Or should I go for integrating these Jquery based packages itself?
Leaflet is great and simple to learn library to work with maps. Fortunately there is a wrapper called vue2-leaflet that make it work with Vue. Regarding your Image this part of docs may useful for you.
In short:
I am trying to find information about text styling inside an NSTextView. Bold, italics, indentation, making a word completely uppercase and setting backdrop colors to certain lines.
Any and all info is welcome. I've been looking around the web for docs on the subject and only managed to find a few things that seem to be part of an iphone framework. I'm sure there must be something out there and that I'm just searching for the wrong words.
A few details:
I am not a developer. I am a motion graphics artist and screenwriter. I do know html, php, javascript, css and several scripting languages (all very similar to javascript) used by different graphics apps.
I am not very proficient in objective-c but I've taken up writing a screenwriting app as a bit of a side project. I've been teaching myself objective-c from a book call Cocoa Programming for Mac OSX and using the code I've created from the examples in the book to create my app using Xcode. Styling text was not covered and I am at a loss as to how to approach it.
Screenplays have very specific formats. Using css I could create this format easily so my first thought was to find out if text inside a NSTextview can have css applied to it. I've not found anything that could answer this. Of course I am probably way off with this approach.
Again, any help or anyone who can point me in the right direction would be extremely appreciated.
Thanks!

You can't do this because it only accept one style.
You have to deal with UIWebView Tutorial for this and use your CSS.
Or you can use some code like EGOTextView. I do not test this but I think it will be the easiest way for you.
i am using Google Fusion Tables and Google Maps to display geographical data (e.g. markers). My map needs to have a legend, for example by inserting a div on top of the map and the layer. As i am not used to work with API of any kind, i got stuck with this legend problem.
I tried several example codes (most of them provided by google), but none worked for me. I guess that the problem of displaying divs on a map has got something to do with either the styling of the map canvas, the div implementation within the body of the html document or with the framework used (google appengine). But this is just guessing. As i am not a professional with coding, i maybe missed a important point. Maybe the folks here can help me out?
Every hint is appreciated. Thanks.
You can have a look at the code and my example [here (deleted)]. There example includes a code which should display a div, but it doesn't. I've taken it from here (Stackoverflow).
The code you're using is v2 of the Maps API. You'll want to use code that works with v3 of the Maps API, since that is the version you're using on your site.
Have you tried the sample code here?
https://developers.google.com/fusiontables/docs/samples/legend
Copy and paste the legend code from this example into your initialize method, remove the old legend code. If this doesn't work, let me know.
Cheers,
for about a year now Google allows you to adjust the styling of their maps according to your needs. They offer a tool which allows for the easy creation of styles too:
Google Maps API Styled Maps Wizard
What I'd like to know is: can this feature of their API be used with MKMapView as provided in the Map Kit Framework? If so, how and at which point would I feed the JSON code which the wizard produces to the API?
If this doesn't work with MKMapView: What's the next best way to include Googles Styled Maps in an app?
Thanks alot!
As far as I'm aware, MKMapView doesn't provide this functionality "out of the box" as the Google Maps API does; the class reference, seems to support this hypothesis. You could re-implement some of the styles using annotations and overlays (see the class reference), but that assumes you have access to the point of interest data. Your success will likely depend on what styles you want to use.
As for the next best way, I opened your link, the styled maps wizard, on my iPad and it seems to work flawlessly. Perhaps you could host a pre-styled map somewhere online and simply show it in your app using a UIWebView? That would obviously limit you in some ways, but at least it would be styled!
I use custom images in google maps markers. I have included google earth control through google earth browser plugin. But they don't show custom images in google earth control? Any way I can solve this problem?
Thanks,
Jayesh
In general, you define your own symbols via Style/Iconstyle/Icon structure first, then you reference them in placemarks using the styleUrl element.
If you have a KML/KMZ that works well with the standalone GE application showing your custom icons, you can load it into the API using some JavaScript like
var networkLink = ge.createNetworkLink('My cool KML/KMZ file');
var link = ge.createLink('Link to My cool ...');
link.setHref('http://www.here.on.the.net/MyCool.kmz');
networkLink.setLink(link);
ge.getFeatures().appendChild(networkLink);
If not you may get the stylemaps into the "internal KML" via some code. For example see here
Hope this helps.
Good luck

Try absolute paths for the marker icon's images. Must be a bug of some sort.
