Hi Najibullah - my apologies that this one is getting out of date, but your workflow should be possible in two steps with QGIS "Raster" menu: 1. Raster --> Projections --> Warp (this will reproject) 2. Raster --> Conversion --> Translate You'll still need to do some raster styling to make the output look the way you want it to. This section of a different tutorial might work for you: ua-cam.com/video/xB-cT_9TwJQ/v-deo.htmlm1s

Thanks for checking it out man!

+Switch Grafico Web Mapbox has released some great documentation since I put up this video - you should check it out: www.mapbox.com/help/create-a-static-map/

+Bill Morris Very Thanks Bill, nice guide!

+cardiacade Unfortunately that totally depends on the accuracy of the GPS unit. A standard iPhone GPS won't have the level of precision you need, but it's possible to manually correct the points afterwards using aerial imagery (OpenTreeMap uses this approach: blog.opentreemap.org/2014/08/26/12-great-questions-about-otm-mobile-apps/). The more expensive option is to use a survey-grade GPS, but those can run to many thousands of dollars.

+Ron Mac Quarrie You are quite correct :)

+Neal Francis Comilan Looks like it's on their roadmap - the Mapbox strategy guy weighed in personally (a rare occurrence) on this very long thread about offline maps: github.com/mapbox/mapbox-gl-native/issues/584#issuecomment-155845085

+Marios Kalogeropoulos They've changed the UI a bit - now it's listed as "description": www.dropbox.com/s/pomlzxh7xbcb5l1/Screenshot%202015-10-13%2016.48.19.png?dl=0

+Bill Morris Thank you very much for your answer. Βut i still have problem. I put at the "description", the example code you send me : <img width="250px" src:“www.greenacres.com/wp-content/uploads/2014/04/blog-wheat.jpg”> Then i put save and i didnt see the photo up to the marker again. Do you know why? Thank you very much.

+Marios Kalogeropoulos Looks like some nitpicky HTML; the doublequotes got turned into backticks on your keyboard, and the "src" option needs to be followed with "=" instead of ":" This should do the trick (note the differences): <img width="250px" src="www.greenacres.com/wp-content/uploads/2014/04/blog-wheat.jpg"/>

+Bill Morris Thank you very much. Ι am a journalist and not a programmer as you see. Did you know if i can put a link instead a photo? Ι want to put news at the marker. And when the user click it, send him to journalism site. Something like a hyperlink or a ref at the html language.

+Marios Kalogeropoulos You'll pick it up as you go :). Looks like you want an anchor tag: developer.mozilla.org/en-US/docs/Web/HTML/Element/a. Something like this: <a href="www.reuters.com/article/2015/10/15/us-mideast-crisis-syria-homs-idUSKCN0S90JG20151015">Syrian army and Russian jets target rebel towns north of Homs</a>

+Yasmin Amer I take back my earlier comment about it working fine - it looks like they changed the UI, but more importantly set the default behavior to show the tooltip only on click. That means you'll have to use the mapbox.js library to play with the basic map interface. Here's an example of images in tooltips that appear on hover: bl.ocks.org/wboykinm/b6e82800999d08140db3

+christopher saunders You first have to choose which projection is better-suited to your map/analysis, the reproject the non-matching vector file to that projection like so: www.northrivergeographic.com/qgis-reprojecting-vector-data. This is a bit of a hassle, but it's important for reasons of geoprocessing accuracy to have all your data speaking the same geographic language. Once you've matched the two layers in the same projection, you can proceed with the intersect operation: infogeoblog.wordpress.com/2013/01/08/geo-processing-in-qgis/

+MataGigantes WOW - many apologies to have missed this for a year. But your question is still as complicated as it was then :) Basically you'll find that they all serve slightly different purposes - Mapbox is great for fairly static data and beautiful cartography, Google has unmatched APIs (geocoding being the biggest differentiator), and CartoDB is the perfect tool for mapping datasets that change a lot or require geoprocessing.

Good call - I was pulling things out of my poorly-organized brain catalog.
