##Whirld

Whirld is an extension of the Public Lab's Mapknitter software. It allows you to upload photos and and combine them into:

  • web "slippy maps" like Google Maps
  • GeoTiff
  • TMS
  • high resolution JPEG
  • plus much much more!

##Prerequisites

Recommended; for an Ubuntu/Debian system. Varies slightly for mac/fedora/etc

Install a database, if necessary. sqlite does not seem to work due to some table constraints.

sudo apt-get install mysql-server

Application-specific dependencies:

sudo apt-get install bundler libmysqlclient-dev imagemagick ruby-rmagick libfreeimage3 libfreeimage-dev ruby-dev libmagickcore-dev libmagickwand-dev

(optional) For exporting, you'll need GDAL >=1.7.x (gdal.org), as well as curl and zip-- but these are not needed for much of development, unless you're working on the exporting features.

sudo apt-get install gdal-bin python-gdal curl libcurl4-openssl-dev libssl-dev zip

Install rvm for Ruby management (http://rvm.io)

curl -L https://get.rvm.io | bash -s stable

Note: At this point during the process, you may want to log out and log back in, or open a new terminal window; RVM will then properly load in your environment.

Ubuntu users: You may need to enable Run command as a login shell in Ubuntu's Terminal, under Profile Preferences > Title and Command. Then close the terminal and reopen it.

Then, use RVM to install version 2.1.2 of Ruby:

rvm install 2.1.2

You'll also need bower which is available through NPM. To install NPM, you can run:

sudo apt-get install npm

However, on Ubuntu, you may need to also install the nodejs-legacy package, as due to a naming collision, some versions of Ubuntu already have an unrelated package called node. To do this, run:

sudo apt-get install nodejs-legacy

Once NPM is installed, you should be able to run:

sudo npm install -g bower

##Installation

You'll need at least Ruby v1.9.3 (v2.1.x preferred)

  1. Download a copy of the source with git clone
  2. Install gems with bundle install from the rails root folder. You may need to run bundle update if you have older gems in your environment.
  3. Create a mysql user called 'myrailsbuddy' that has the password, 'mypass'
  4. Initialize database with bundle exec rake db:setup
  5. Install static assets (like external javascript libraries, fonts) with bower install .
  6. Start rails with bundle exec passenger start from the Rails root and open http://localhost:3000 in a web browser.
