Use this repo to make ready to go story maps with either Leaflet or MapboxGL JS mapping libraries.

• Leaflet is a robust mapping library to load rasters tiles. It's development has been instrumental in bringing open source to maps and anyone wanting to make a map.
• MapboxGL is the next stage in developing web maps as it uses vector tiles and many awesome features like handling large datasets and styling maps on the client side.
• If you're interested in more, go here

• One of the cool things about open source is that we can distribute our work with others with no license (free). If you got an amazing project you're developing, others can join in and contribute.
• One of the ways we can distribute code and works are with platforms like Github! Which is a code hosting platform for version control and collaboration, its like you sharing your Google Doc with others to edit. If someone makes some mistakes on your document and you want to return back to the version 3 days ago, you can. This is similiar.
• There's more to Github, but in this instance we are gonna use this platform to host our maps.
• So let's make a map that will be live in a matter of minutes.

1. In order for you to host maps on github you need an account
2. Log in to your account and come back to this repository (A repository aka repo is used to organize a single project, they can contain folders, files, images, datasets, pretty much anything you need for your project). In fact you are at the repository right now!
3. We need to fork this repository to your account, because right now its being hosted through maptimeLA's account. Creating a fork is producing a personal copy of someone else's project in this case maptimeLA's. Want to know more about forking?
4. Fork this repo by clicking on the button labeled fork.
5. A window will appear and will ask you where you want it forked, select your account and watch it fork!
6. Once complete, it should load the repo with your account name and the name of the repo. For example user cityhubla has forked the storymap_tutorial from maptimeLA
7. Now we're close to getting some maps up and running but we need to change some things because they are referencing maptimeLA's repo.
8. Click on the settings button
9. In the settings, scroll down to the section labeled Github Pages. You will notice options for getting github to host your files (ie maps)
10. In the Source option, select master branch and hit save.
11. The page will reload and scroll back down to the Github Pages section, you will see a note that says, `Your site is ready to be published at...' with a link. This is your link to your pages which you can hand out to friends and family.
12. Now we need copy this link and change it at the front page, know as the readme. Copy the link, scroll up and select the storymap_tutorial name next to your username. This will take you to the readme.
13. At the top of the page you will see Demonstration Map https://maptimela.github.io/storymap this needs to be updated with your link. To change it click on the edit button on the far right of the page and replace the link with yours and save.
14. Now you have a link to a live web map you can modify! Click on it and see a storymap of LA! (Note: It may take Github a minute or so to reflect the changes to your account, the map may not load. Give it some time and it should appear.)
15. This particular webmap index.html is using the mapboxGL javascript mapping library.

You will notice in your repo, two folders named leaflet and mapbox, these contain example maps using these libraries.

You can try out the maps here,

• 1_leaflet | This is a very basic map, if you look at the code, you can see that just a couple lines of code can get you a map. To run the map, you need to copy https://<username>.github.io/storymap_tutorial/leaflet/1_leaflet.html, paste it into your web browser and change <username> with your username.
• 2_leaflet | This is a leaflet map with additional code to make it into a storymap. You can modify the code, and the text to make your own. To run the map, you need to copy https://<username>.github.io/storymap_tutorial/leaflet/2_leaflet.html, paste it into your web browser and change <username> with your username.
• 1_mapboxgl | This is a very basic mapboxGL map, if you look at the code, you can see that just a couple lines of code can get you a map and it's very similiar to Leaflet, except mapboxGL has many new features. To run the map, you need to copy https://<username>.github.io/storymap_tutorial/mapbox/1_mapboxgl.html, paste it into your web browser and change <username> with your username.
• 2_storymapboxgl | This is a very basic mapboxGL map, if you look at the code, you can see that just a couple lines of code can get you a map and it's very similiar to Leaflet, except mapboxGL has many new features. To run the map, you need to copy https://<username>.github.io/storymap_tutorial/mapbox/2_storymapboxgl.html, paste it into your web browser and change <username> with your username.

If you're new to geoferencing, or digitizing scanned maps, like historic maps for geospatial uses, check out slide show.

This part is accessing historic maps provided by the David Rumsey Collection which has a very nice collection of historic maps, many of them are georeferenced for your use and the tiles are hosted and served from the collection. Meaning all you need to do is find a map you like that is georeferenced and get the link to add it your map code, and you have an historic map! Other cool features from the Collection, is an online tool for you to georeference maps in their collection.

1. The David Rumsey Collection has a nice collection of scanned maps made by the GW Baist Company, which are real estate surveys from the early 1920's.
2. Let's choose this map, showing a large train yard which is now the Los Angeles State Historic Park, you can see the LA River and Solano Canyon.
3. Click on the brown button labeled VIEW IN GEOREFERENCER to load a new window where you will see the map as an overlay on a basemap.
4. From here you select the `What next? button at the lower right corner
5. From there you will need to get the links so you can add it to your map. Select the Get links button
6. Select and copy the link in the area labeled XYZ Link
7. And then goto your map code and either replace the layer or add another layer.
