Rapa Island, North Shore - Other Precision (Ikonos) Map with Digitized Hydrography Layer (1:1,250)
Sure, I've been busy with family, friends and 12 dozen tamales served all day Christmas day at my home. Come Christmas evening I was still entertaining guests and wishing I could continue working on my current mapping project, Rapa Island. I have mapped this island a number of times, each time not completely satisfied with the finished project. So I've decided to work on this island one more time. First I redigitized the shoreline working at scales between 1:1,250 to 1:850 using a hi-res Ikonos image. After completing the shoreline, I decided to work on the island's hydrographic layer. Initially I've classified each valley as a potential stream course. The island has a number of permanent streams fed by frequent rain storms and springs. Most of the streams I've currently mapped will be reclassified as intermittent.

I've mapped most of the hydrographic layer over the last 5-days, actually over the last 5-evenings. The hydrography of the western portion of the island remains to be digitized. I hope to have the layer completed within the next few days. When it is finished, I intend to digitize the vegetation layer next. I'll keep you informed as to my progress.
Enjoy! Merry Christmas and Happy New Year!
