Tactical Pilotage Charts

barangkali ada yang ingin iseng convert beberapa peta TPC dari Univ Texas di Austin, jadiin ubin / tile, sehingga bisa menjadi basemap dari WebGIS (misalnya: leafletJS atau Google Maps API)?

Making shaded relief from digital elevation models (DEMs) in QGIS: a British Columbia perspective

reblog-ed from Wandering Cartographer, sedikit tentang DEM, SRTM, EPSG, QGIS blending

The Wandering Cartographer

Who would not agree with Tom Patterson, creator of the fabulous shadedrelief.com website, when he said, “There is no more important component of a map than the shaded relief.”

But the topic of creating your own shaded relief from a DEM is rather complex, so I’ve made a few assumptions in this how-to. I’m assuming:

  • you know your way around QGIS (I am using QGIS 2.18 for this post)
  • you’re familiar with the idea of projections, and re-projecting raster data

    • UTM Zone 9N/WGS84 = 32609
    • BC Albers = 3005

Six Steps to Get a GIS Internship During Undergrad

Pavise

Finding an internship in college can be very daunting and time consuming. It took me 7 months of active searching to get my GIS internship during my undergrad. Depending on your location, university, and personal network this search time could vary significantly. Below, I’ll give you clear and actionable steps that you can utilize during your search for an internship. It’s important to note that these steps build on each other. As you move on to later steps, I suggest you keep following the preceding ones as well.

1. Talk with your professor

Visit your professor during office hours and let them know you’re looking for a GIS internship. Your professor is probably the single most important person when it comes to getting a GIS internship for the following reasons:

  • They have a good grasp of your skills and abilities.
  • They are a part of a larger GIS network in…
