Hello. Thanks for mapping.
Urgent request.
Please use the MAXAR P imagery to map from. The Bing Imagery, which you are using now is very old and outdated. Maxar P is listed in the instructions as the imagery to be used. On attached webpage you cans read how you can select another imagery
Best regards

Hello Thanks for mapping

Your mappings are fair despite the image was not that easy to work from
A few remarks
Do not include the shadow of a building into your mappings. The dark/black spot beneath a building. It indicates whether an object is above ground level or not

Please square all buildings you map with the Q key in iD editor in future mappings. You can also keep the Q key pressed down and select the buildings each after each other (except the round buildings) You squared just a few buildings.
Best regards

Sometimes there seems to be a kink in the middle of a roofline at the height of the ridge in the roof when it's a gable roof.
This is caused by the angle at which a satellite image was made. You can simply map this as a rectangular (4 nodes) roof.

Hello Goat1. Thanks for mapping
Did you not read the instructions which imagery to be used? You used the Bing imagery which is over 10-15 years old. The MAXAR P imagery is most recent and shows more buildings than Bing. Please pick up this task again and map the missing buildings, Thanks

Hello. Thanks for mapping here.
a request. Please be more precise at next mappings. you map rather inaccurate and oversized
Best regards and keep mapping

Hello Dwart. Thanks for mapping here. I review work of (new) mappers to check if they comply with the instructions and are of a good quality
A remark. There is a difference in mapping a rectangular or a round building. Most buildings are strict rectangular or L shape. they needs just 4 or 6 nodes to draw (Square each building with the Q key. A round building can be drawn by a triangle over the outside of the round hut and pressing the O key while the mapping is still selected.
When you take a look to the schadow the building makes it is obvious to see the shape of the building. There are also oval shaped roofs. underneath the buildings are mostly rectangular. so draw these as rectangular building.
You mapped a small area in the middle as farmland. This is a fenced piece of land in the settlement to keep livestock . (Corral)
No need to map.
Best regards and keep mapping

Hello Shaikj solaiman
I checked this changeset with the Bing imagery and it certainly shows a river
Take a look here
osm.org/#map=17/-15.302455198445356/23.140516806777004
and open it with the Bing Imagery, Yes Maxar shows dry ground, but Bing can be as old as over 10 years.
Best regards

Hi Shaikh Solaiman
This must be tagged by accident. Residential areas are never multipolygons.
you could solve this by yourself.
Another question. I validated quite a number of tasks on this project (59). Which task is it? I cannot believe I left such a mess behind. When I run the validation tool on this changeset I see 16 warnings and 58 not squared buildings and 1 other issue.
Best regards

Hi, Shaikh solaiman.
Did you seen when this task has been mapped.? 9 month ago.
Maxar S did not exist on that time. It came available early july this year.
Feel free to adjust my mappings.
Best regards
btw. I do a lot of validating work on project 5741 (Tanzania)on which you mapped many tasks
Please be more precise in mapping buildings. Oversized. Mapped many square buildings as round huts. I did not bother you with that because the mappings took to long ago. So I corrected them where needed.

Hallo ReBoNL Dit zijn inderdaad geen gebouwen. Je hebt al meer reacties gekregen hoe je gebouwen kunt herkennen.
Ik heb deze gecorrigeerd.
Ik controleer de rest van je changesets ook en corrigeer ze zonodig.
vriendelijke groeten

Hello ReBoNL. Thanks for mapping here.
I had to revert all your mappings here exept those in the settlement in the south east.
You mapped lots of irregularities or bushes as buildings. See my previous comments about how to determine that something is a building
Best regards and keep mapping

Hallo. ReBoNL. Bedankt voor het mappen hier. Even een opmerking. Je hebt gigantisch veel ,647,bomen, struiken en objecten gemapt als gebouwen. Zonde van je tijd. Kijk altijd naar sporen van menselijke activiteit zoals zanderige (lichte) plekken of paden. Zeker in de savanne zoals hier.. Ronde hutten vind je vooral in de omheinde nederzettingen. Herkenbaar aan een beetje grijze cirkel met een mooie ronde schaduw ernaast. Bomen/struiken zijn hoofdzakelijk groen met een onregelmatige schaduw. Ik zal het aanpassen.
ik heb deze changeset teruggedraaid,
Nomaals. Sorry voor al je werk.
Vriendelijke groeten en blijf mappen.

Hello Niyaz. Thanks for mapping here.
A request. Will you please square the rectangular buildings with the Q key in ID editor. You missed quite a number.
Best regards and keep mapping

Hello again. I reviewed this mapping as well.
Here you did not square the building and correct the offset of other buildings before you start mapping. When you overlooked, that the building you mapped becomes over 5 mtr out of its real position
btw There are more buildings in the surrounding which could be mapped.
Best regards

Hello Abdooo. Thanks for mapping.
I review tasks of (new) mappers to check if they comply to the requirements, are free of errors and of a good mapping quality.
Here you map a cluster of 3 buildings as 1 building. Please be more accurate in mapping.
Here you can see your mappings (green) and the adjustments which has been made

Hello chulia. Thanks for mapping.
A remark. your mappings are rather inaccurate and not squared. Please improve your mapping skills.
Best remarks

Hello. Thank you for mapping. A request.
Try to map individual buildings as 1 building .You tend to map clusters of buildings including ground level as 1 building.
This need special attention and correcting work.
Best regards and keep mapping

Hello Yostina 99.
Thanks for mapping
I review tasks of (new) mappers to check if they comply to the requirements, are free of errors and of a good mapping quality. On the attached pictures you see your mappings
https://drive.google.com/open?id=1B1Y-6Xxk5k9F6UOMVAlXwDyHzljt4VUO
I have some remarks.
Marked with 1. Should be straight rectangular mapped. Most buildings are straight forwarding rectangular. Do not follow the outlines of trees, but extrapolate the walls of a building.
2. Do not connect nodes of buildings to each other. Be sure they stay separate.
3.Here you map 2 buildings as being 1 building. Please map them separate.

Do not include the shadow of a building into your mappings. The dark/black spot beneath a building. It indicates whether an object is above ground level or not

Please square all buildings you map with the Q key in iD editor in future mappings. You can also keep the Q key pressed down and select the buildings each after each other (except the round buildings) You squared none.

On this page you can see your mappings (red) and the adjustings (green) and new mappings (Yellow) which has been made

Hello I reverted this changeset.
Your mappings are so inaccurate that is cost more time to correct your mappings rather than mapping them from scratch.
Best regards

Hello Andrea. Despite you worked on this a year ago it is necessary to react on your mappings.
I am sorry to tell you that your help on this project is not what we could be expected from a mapper.This is not a computergame but a serious attemt to help NGO's and people with maps they can rely
You have showed to have lack on mapping skills and instructions how to map
I retmove your mappings.
