Todd thanks again. I’m leaning toward hiring the guys (Total Habitat) that wrote this guide to be consultants on my project.

NSP project update. I am going to hire a consultant to provide design guidance on the pool systems and material selections. I will still be the designer of record and also manage the construction aspects of the project. I’m choosing between two companies, BioNova and Total Habitat out of Kansas. I am leaning toward Total Habitat because I like…[Read more]

Texas has five state plane zones…with sp 1 the most northerly zone, sp 5 is the most southerly…knowing the location of the project, which county/city it is in, will help to locate it in the appropriate State Plane zone…there are ways to match up unknown projections to lat-long, but that discussion is way beyond the scope of this discussion t…[Read more]

How accurate is the etrex?  Just as AG has posted above, I’m now wondering if she could add two or three more gps points to her own data set [with the etrex] that appear on the survey and then use the acad align command to get her data points aligned to the survey.

I would turn the survey file into a template after erasing all the data, then re…[Read more]

How many points are you converting?  100, 200, 5000????  The etrex collects data in Latitude-Longitude, WGS84 only…the data can then be converted from the coordinate system to any other coordinate system on the fly in the etrex…btw this is the abbreviated explanation.   However, the etrex is not very robust when converting coordinates… NAD…[Read more]

One thing that you can do on your own is to take your GPS and occupy some of the known points that are in the other datum and determine the difference. Then you can put all your GPS points on a separate layer and make a block out of them. Move the block using one of those matched points as the base point and moving it to the corresponding point in…[Read more]

a sad article, but then what do you expect from the guardian ?

or a surveyor forum ? They should meet that situation daily and know the best fix

Would suggest that you find a friend that has AutoCAD Map or whatever replaced it. That program had the ability to translate and adjust coordinate systems. I know it isn’t much help but I have had personal experience with this very issue years ago and that is how we addressed and resolved the issue.
Best of luck.

I think we are supposed to know which is appropriate, how much, and where, etc. then articulate the programmable space. It reminds me of that other topic “food for thought (or not).”

I just found it confusing. What was the writer really advocating? (One commenter tried to translate it but I’m still not sure). Isn’t it exactly the urban lovers who want to save the city by making it more habitable by including both walkable and green spaces? They aren’t advocating some moratorium on new buildings, not as I understand it.

Haha @Robert, all I said was BMP’s are  written into law, through NEPA, I think, which is Federal. So it applies across the country as far as I know. Have you never had to design stormwater systems? I do work at the state scale, so perhaps if you do a lot of residential you don’t deal with stormwater so much, but BMP’s are still a really good…[Read more]

Go to http://www.cadtutor.net/forum/forum.php and post your question.  
You’ll likely get way better help there than here.

Thanks, Tosh, interesting read.
Leaves me feeling, though, that “thinkers” spinning ideologies about ideal spaces for people ought to observe people using spaces. They may despise these green spaces but people love and use them. Stupid stupid people.

Probably so: I’m not doing the point identification just inputting data so am trying to work with the data provided.  :-}

Thank you.  I’ll read up and try downloading.

It would seem that the  Garmin eTrex 30 GPS is far less precise than the difference between these two datum references based on everything I’ve read about the instrument.

Well put Andrew.

Omar – it seems you have skill sets that are valuable in the profession both computing and (presumably) broader conception of ‘sustainability.’  Many LA graduate programs (at least in the US) are geared toward those of us who studied something else.  For example, my classmates had undergraduate degrees in art, english, art h…[Read more]
