 @_slack_fatiando_UMFSBQVMG:matrix.org | Nice! Please feel free to invite them to the Slack channel! | 18:12:05 |
| @_slack_fatiando_UMFSBQVMG:matrix.org | And, since you are using the new prisms_layer feature, would you add some feedback to the Pull Request (https://github.com/fatiando/harmonica/pull/186)? While coding and designing sometimes it's easy to lose track of usability, so any feature that you might want to add, or change something in the documentation are very welcome. For example, making the prisms layer to copy the topography + bathymetry grid seem a little bit annoying, maybe we can add a method to the PrismsLayer class to do it for us. What do you think? | 18:15:19 |
 @_slack_fatiando_UT0BDHKPE:matrix.org | yes i will | 18:16:05 |
 @_slack_fatiando_UMGLPTLAW:matrix.org | This looks really interesting! Would be great to have a notebook example to put it all together to go from observation to complete bouguer anomaly for both ground and satellite data. How fast is the terrain correction computation compared to oasis? | 19:02:54 |
| @_slack_fatiando_UT0BDHKPE:matrix.org | would check, I need to ask to a colluegue of mine. Personally I do not have access to it | 19:04:09 |
| @_slack_fatiando_UMGLPTLAW:matrix.org | no worries, how long does it take for your example? | 19:10:24 |
| @_slack_fatiando_UT0BDHKPE:matrix.org | i did not check the time precisely but i would say for a cellsize of 250m and a grid of 200x200 roughly about 5 minutes | 19:11:34 |
| @_slack_fatiando_UMGLPTLAW:matrix.org | ok not too bad, thanks | 19:12:40 |

This looks really interesting! Would be great to have a notebook example to put it all together to go from observation to complete bouguer anomaly for both ground and satellite data. How fast is the terrain correction computation compared to oasis? Absolutely Craig Miller! I see that notebooks with full workflows is a very nice addition to the documentation. For this specific feature (terrain correction) we would need to merge the PR first, remember that Lorenzo is running it from a branch I opened to upload the new code. | 19:51:32 |

(edited) ... new code. => ... new code.
But whenever it's merged we can start working on a notebook for it. In fact, Lorenzo could add his application, if that's ok with you. | 19:52:31 |

| @_slack_fatiando_UT0BDHKPE:matrix.org | Yes will be ok for me. Just try to clean thinks a little bit… | 06:43:57 |

| @_slack_fatiando_U013EU24QKH:matrix.org | Hello everyone, greetings to all of you, i'm a student from indonesia. now i am working with gravity disturbance data from curtin university (GGMPlus), i've read the 'gravity_disturbance_topofree.py' repo on harmonica github. after applying the topo-free, do i need to do terrain correction like station gravity? can i generate bouguer anomaly from gravity disturbance data? many thanks... | 09:25:48 |

i did not check the time precisely but i would say for a cellsize of 250m and a grid of 200x200 roughly about 5 minutes 23 minutes for about 70k cells. in a standard laptop | 11:17:43 |

this is the oasis workflow ( free-air and terrain correction computed in oasis) sinoce the survey dataset consist of >45000 stations (bottom), for the harmoica approach i have blockreduced the dataset to 5000 samples (top) | 11:29:41 |

| @_slack_fatiando_U0156QCM6AH:matrix.org | Nice work too Lorenzo | 12:09:58 |

Congrats Lorenzo! That looks really nice! It's great that you have tested reproducibility. Have you block reduced to speed up the computations? Or is there any other reason? | 13:18:36 |
