-===== TODOs =====
-<todo @owen #osmith:2020-03-13>Write a tutorial using the sample data like CanoPy for dummies</todo>
-===== CanoPy Tutorial For Dummies =====
-**Sample  Data Contents:**
 The sample data will contain 3 folders titled ‘naip’, ‘data’, and ‘Outputs’. The ‘data’ folder contains the Georgia physiographic regions shapefile, the NAIP Quarter Quad (QQ) polygon shapefile in addition to the TIFF file which will be used for snapping. The ‘naip’ folder will contain 4 input QQ NAIP tiles that form a 2 x 2 area. The ‘Outputs’ folder contains the outputs that are created by Textron’s Feature Analysis software for each NAIP QQ in the sample dataset. This is included as this tutorial does NOT go over the process of using Textrons Feature Analyst but rather the process of using the CanoPy Python module.
-**Steps:**

   - Either clone the repository using Git in the terminal with the below code <code>

     * After it is finished the ''naipqq_layer'' will now contain the '' naipqq_phyregs_field'' which will be titled ‘PHYREGS’ in this case. Each NAIP QQ will now have the region id’s of each region it is in.
-    * The secondary purpose of ''canopy.assign_phyregs_to_naipqq'' is to calculate the area in square kilometers of each physiographic region. The ''phyregs_layer'' will now contain the '' phyregs_area_sqkm_field'' which will be titled ‘AREA_SQKM’. The ‘AREA_SQKM’ field will be used with the ''generate_ground_truthing_points'' function.

   -  Next you will assign the phyreg_ids, which in our case will be:<code python>
 phyreg_ids = [3]

   -  Next you will reproject all input NAIP tiles to the projection specified by the '' spatref_wkid'' in ''canopy_config'' which will be [[https://spatialreference.org/ref/sr-org/usa-contiguous-albers-equal-area-conic-usgs-version-landfire/|WKID-102039: USA Contiguous Albers Equal Area Conic USGS version.]]. Use the following code to use the reprojection function<code python>
-canopy.reproject_input_tiles(phyreg_ids)
+canopy.reproject_naip_tiles(phyreg_ids)
 </code>
     * Reprojected tiles with the suffix ‘rm_’ will be saved to ''.../CanoPy_sample_data/2009 Analysis/Blue_Ridge_Mountains/Inputs'' which will have been created by the function.
