157178650 | 9 months ago | Sorry; I accidentally omitted a change description. I am in the process of pulling the Walpole Island First Nation boundary off of the International Border. This is work in progress. |
156553949 | 10 months ago | Ky_AT, you fixed the issue in changeset 156567714 at 07:36 Eastern Daylight Time (almost 6 hours ago). Thank you for that. I am not sure there is really any more analysis to do. Everything is fine now. |
156553949 | 10 months ago | Ky_AT, you broke Lake Saint Clair with this edit.

122095055 | about 3 years ago | The boundary of Carcross I.R. No. 4 was first surveyed and demarcated in 1959. Survey record is "CLSR 50051 YT".

120812871 | about 3 years ago | In 1984 the Inuvialuit Final Agreement adopted the intersection of the northerly bank of the Kugalak River and the shoreline of Penny Bay in its definition of the Holman 7(1)(b) parcel at the western end of the Wollaston Peninsula on Victoria Island.
Between 1984 and 2015, erosion caused the mouth of the river to move about 1500m south; this is evident when comparing old and new satellite imagery.
Based on features shown on the survey plan, it is possible to determine the location of the arrow with an accuracy of about 10m. If we believe current ERSI imagery, the spot marked by the arrow is now under water due to erosion. It is not clear if the current boundary should be based on the 2015 survey or if it should move with the river. I expect it would take a team of lawyers to figure that out.
In this changeset I have redrawn the entire marine boundary from mainland Canada to the Kugalak River. The eastern termination point is within about 20m of the spot marked by the arrow on the 2015 survey plan. The nodes are plotted on a geodesic line which gives the marine boundary a slight curve when viewed on a Mercator map. |
104020825 | about 4 years ago | The areas of natural=reef in the vicinity of Bove Island were originally added by Ben&Sarah as part of changeset 84304324. I have removed them because I am not convinced the "reef" is the best term to describe an area of shallow water in a fresh water lake. Also, areas of shallow water in fresh water lakes are not normally mapped in OSM so I don't see the point of making a special exception for the shallow water near Bove Island. |
103533791 | about 4 years ago | The western end of the BC/YT border has never been surveyed and therefore there is no survey monument at the BC/YT/AK tripoint.
|
100021231 | over 4 years ago | Actually the removed way was called "old Dehcho - South Slave boundary". |
99255007 | over 4 years ago | Thank you for pointing out the stray colon. I have removed it from all the survey monuments that I added over the past few days. |
99478564 | over 4 years ago | In 2014 the Survey General Branch of Natural Resources Canada decided that the Northwest Territories / Nunavut boundary should commence at survey monument 157. All the monuments between 157 and 2-1 (201) were installed in September 2014; they are laid out in a 472 km geodesic line. |
99237677 | over 4 years ago | Correction to my previous comment:
|
99237677 | over 4 years ago | This changeset includes survey monuments between 120°40′51.00″W (NAD27) and 110°40′00.00″W (NAD27). The monuments were installed in 2011 and lie in two geodesic lines.
|
99233289 | over 4 years ago | I guess I can't edit my previous comment. The sharp turn is at Monument 4-30 (not 4-20).
|
99233289 | over 4 years ago | Nunavut Act stated that this part of the border should be at 120°40′51″W longitude.
|
98939785 | over 4 years ago | There is a small problem which I cannot resolve. The road signs appear to show a boundary formed from two straight lines.

98939785 | over 4 years ago | FYI. The old shape of the time zone boundary in SE Labrador was clearly based off a KML file that I created and uploaded to the Internet in 2007. That was prior to the completion of the HWY system. Things have changed since then; they highways were completed and the government erected a time zone change sign (complete with poorly drawn map) along HWY 510. |
