OpenStreetMap

On this day in our cwts++ class(September 13, 2018) we learned more about Mapilliary and OpenStreetMap, on how we use it properly and also we did some validation in JOSM. On our leaderboard, the class has already made 23,000++ edits in mapping. Its like 36,535 basketball courts. I was happy because our hardwork in mapping had a remarkable result. We were also taught on how we can improve our mapping skills and how we can map more precisely.

Some of my classmates are doing a task in the Philippines “PH road network improvement” in which they have to find out where the missing roads in the Philippines. Mapping is very fun and interesting but it’s hard because some of the imagery are cloudy and some buildings are really hard to be found. And our instructor discussed about the “SatNav System” or “Satellite Navigation System” that allows small electronic receiver to determine their location. And the “GPS Satellite Constellation” consists of a constellation of satellites transmitting radio signals to users. And also our instructor discussed about how GPS works. Weather, time of day and precipitation may affect the radio signal.

After the discussion we had a individual appraisal and by group, we show and tell to our instructor about our neighborhood edits using OpenStreetMap and JOSM. The instructions are login to your OSM account and locate your neighborhood after that, download the data in JOSM and filter your edits. We validated, and fixed our issues in our neighborhood using JOSM and also we double checked our fieldpapers that we marked so that we can review our edits in JOSM to resolve some errors. When you want edit maps using JOSM, you could download the map and you could use it online while iD editor in OpenStreetMap needs wifi access. Some of my classmates kave done a lot of edits in their neigborhood, they found out what establishments that are not specified in the OpenStreetMap.

There are some issues that our instructor showed us and asked us on how we can resolved it. We validated task 4993 in Lake Sebu, SCO, PH. We used the JOSM editor to validate our classmates’ edits. In this session of cwts++, we have learned a lot like the website Maproulette which our instructor introduced but sadly only few of my classmates can validate because they finished their assigned task and we had a seatwork to find a funeral or memorial homes and double checked the tags.

Every session that we enter gives us more knowledge that we need in mapping. I hope to learn and contribute more in the upcoming sessions. I would also like to thank our instructor, Mr. Erwin Olario for teaching us new things and knowledge in this field!.
