Re: Manipularea seturilor de date LIDAR

Interesant articolul. Am scris si eu cateva articole anul trecut in Market Watch (o revista care nu e tocmai de profil dar care incearca sa prezinte solutii IT la foarte multe aplicatii ce se regasesc pe piata romaneasca):
http://www.marketwatch.ro/index.php?do=2&tl=0&ar=2574&viz=true si http://www.marketwatch.ro/index.php?do=2&tl=0&ar=2457&viz=true
Dintre toate aplicatiile folosite, cele ale companiei finlandeze TerraSolid mi s-au parut cele mai rapide.

Stii ca am mai discutat despre modulul acela r.surf.rst - ai reusit sa-l instalezi? Merge doar pe Grass-ul de Linux, daca nu ma insel.

Salutare,

Foarte util articolul de pe site. Mentionez ca lucrez si eu cu date
LIDAR de o perioada de timp. Sunt foarte exacte si foarte
"obositoare" pt un desktop mediu :D.
in fine...as dori sa va intreb : cum pot uni mai  multe fisiere ascii
(de tip xyz) intr-unul singur sau cel mult 2-3. Am foarte multe
fisiere ascii (peste 1000) si imi vine greu sa le procesez pe toate.

O zi buna!

Cu respect,
geogr. Adrian Covasnianu

Poti folosi UltraEdit32 (are niste functii append, dar ma uit maine la birou peste cum exact se poate face asta) sau cu Windows Commander 7.0 (stiu ca si el are o functie "append" dar n-am decat un 6.03 acasa, din pacate).

Dar am o intrebare: de ce vrei sa le unesti? Eu m-am chinuit sa le sparg in mai multe fisiere pentru ca erau foarte mari.

Cu stima,
Mihai

Oh god, cineva manipuleaza LIDAR si nu poate .txt-uri ASCII ?!
nu pot sa cred ...

cat fis1.txt .... fisN.txt > final.txt
sau
cat *.txt > final.txt

 Daca vrei sa omiti cate ceva afara (e.g antet sau comentarii):
cat fis1.txt .... fisX.txt | grep -v 'randulcutextuldeomisafara' > final.txt

  "pipie" aka semnul "|" cu grep il poti repeta de n ori pt fiecare linie de
care vrei sa scapi.

 Daca vrei sa omiti paragrafe intregi foloseste "sed" in loc de "grep",
merita sa pierzi 15min pe google pana te prinzi cu "sed" daca doresti
chestii mai
avansate de procesare seriala text, scriptul iti ramane forever si iti merge
dintr-un
"enter" poate mai primesti inca 1.000 de ascii-uri, ca sa nu mai vorbim ca e
atat de banal
sa invarti ASCII-uri incat data aviatoare' o faci din memorie in sub 10
secunde ...


 Daca ai nevoie si de un shell (exclus DOS) sa le aiba pe toate pe win32:

"Oh god, cineva manipuleaza LIDAR si nu poate .txt-uri ASCII ?!

Buna ziua domnule...

Care este problema? In primul rand iti multumesc pentru articolul
postat pe site. Foarte cuprinzator. In al doilea rand te intreb daca
ai vreo problema? Sincer consider ca DA.
Scopul definit al acestuia forum (consider eu) este acela de a
schimba pareri, opinii si a invata ceva nou in ale SIG-ului si nu
numai..
Nu inteleg de ce unele persoane raspund in asemenea mod.

Intrebarea pe care o aveam...era f simpla. Doream sa unesc niste
fisiere. Nimic mai mult.

Multumesc inca o data.

Cu respect,

Adrian- "incepator in ale unirii de fisiere ASCII". :D

Revin totusi la intrebarea mea, daca nu te superi: de ce vrei sa unesti fisierele respective? Pentru a-ti iesi un DTM compact? Cam cate puncte sunt intr-un fisier? Motivul pentru care te intreb e ca am fisiere si de 1.5 mil. de puncte (vorbesc de un grid de 1x1 km, cel mult 2x2) si am preferat sa nu le unesc pe toate intr-unul singur.

Mihai

Nu eu l-am postat, dar si eu ma bucur pentru el.

>In al doilea rand te intreb daca
> ai vreo problema? Sincer consider ca DA.

  Chiar atata suparare pe un subiect ?

   Ok, imi cer scuze, intentia aici era pe subiectul "Exclus DOS sau
WinCMD",
cat despre LIDAR inca iau lectii si nici dispun de toolurile proprietare ale
lor.

   Adrian, eu nu stiu sincer ce a deranjat pe subiect, mai ales ca din cate
am inteles pe aceasta lista e vorba
de alternative la cele deja mult prea bine cunoscute solutii mai mult sau
mai putin comerciale, plus credeam ca
mai e vorba de a impartasi experienta atat aia placuta cat si cea neplacuta
restul lumii (acest grup), credeam c
a exista si un mic act de rebeliune pe subiectul acesta si ca ne putem
permite de a fi intre noi macar daca nu in
sferele inalt academice cateodata in afara  tiparului. Am scris pentru ca
chiar am avut o frustrare mai demult
in a manipua fisiere ascii cu continut divers, vroiam sa imparatasesc acest
lucru.
  Era o aluzie funny LIDAR vs ASCII, ce am scris acolo si nu tinteam
persoane cu acel rand, sau nu stiu
ce altceva s-a inteles, dar eu sincer de foarte multa vreme tintesc
continutul tehnic la un mail si mai putin
ma intereseaza latura psihologica, si demult nu mai etichetez persoane sau
grupuri.


> Multumesc inca o data.
> Cu respect,
> Adrian- "incepator in ale unirii de fisiere ASCII". :D

  Fara suparare, mailul meu se adresa exclus "DOS" sau "UltraProEdit/WinCMD"
si imi cer scuze inca odata daca am secat pe cineva cu asa ceva, desi am
tendinta
de a aborda lucruri mai "seci" asa asa cum reisese din articoul postat pe
earth.unibuc
cu acea consola si tooluri in mod text, si alte arcticole diverse.
 Ca sa ma introduc mai bine, si sa se cunoasca intentille mele eu provin
dintr-un mediu pur inclinat
spre dezvoltare soft cu o oarece experienta.

Cu prietenie,
Cristian ~ "Incepator in manipulare date LIDAR"

PS:
In DOS  ar veni ceva de genu:
copy a.txt /A  b.txt /A  final.txt

Salutare,
Un program care lucreaza cu fisiere foarte mari este FileMaker, dar nu
este free. Nu stiu prea multe despre el insa dca vrei sa afli mai
multe iti dau adresa lor http://www.filemaker.com/.
Sper sa te ajute.

Florin.

Salut Mihai,

Am instalat Grass-ul pe platforma linux, insa nu am incercat inca sa
fac interpolari sau alte chestii. Incerc sa ma prind incet incet cum
functioneaza.

In reply to this post by Florin Iosub
Eu, din pacate, n-am avut timp sa-l instalez decat pe Windows. Instalarea pe Linux inseamna sa sap si nu prea am timp, am folosit Linux-ul acum mult timp, prin facultate :)

Ma interesa sa stiu doar de modulul r.surf daca ti-a mers si ai incercat ceva interpolari. Eu nici macar nu stiu cum arata, insa sunt foarte curios daca stie sa faca ce se lauda creatorul sau.

Chiar atata suparare pe un subiect ?

Ok, imi cer scuze, intentia aici era pe subiectul "Exclus DOS sau
WinCMD",
cat despre LIDAR inca iau lectii si nici dispun de toolurile proprietare ale
lor.

Adrian, eu nu stiu sincer ce a deranjat pe subiect, mai ales ca din cate
am inteles pe aceasta lista e vorba
de alternative la cele deja mult prea bine cunoscute solutii mai mult sau
mai putin comerciale, plus credeam ca
mai e vorba de a impartasi experienta atat aia placuta cat si cea neplacuta
restul lumii (acest grup), credeam c
a exista si un mic act de rebeliune pe subiectul acesta si ca ne putem
permite de a fi intre noi macar daca nu in
sferele inalt academice cateodata in afara tiparului. Am scris pentru ca
chiar am avut o frustrare mai demult
in a manipua fisiere ascii cu continut divers, vroiam sa imparatasesc acest
lucru.
Era o aluzie funny LIDAR vs ASCII, ce am scris acolo si nu tinteam
persoane cu acel rand, sau nu stiu
ce altceva s-a inteles, dar eu sincer de foarte multa vreme tintesc
continutul tehnic la un mail si mai putin
ma intereseaza latura psihologica, si demult nu mai etichetez persoane sau
grupuri.

> Multumesc inca o data.
> Cu respect,

Fara suparare, mailul meu se adresa exclus "DOS" sau "UltraProEdit/WinCMD"
si imi cer scuze inca odata daca am secat pe cineva cu asa ceva, desi am
tendinta
de a aborda lucruri mai "seci" asa asa cum reisese din articoul postat pe
earth.unibuc
cu acea consola si tooluri in mod text, si alte arcticole diverse.
Ca sa ma introduc mai bine, si sa se cunoasca intentille mele eu provin
dintr-un mediu pur inclinat
spre dezvoltare soft cu o oarece experienta.

Cu prietenie,
Cristian ~ "Incepator in manipulare date LIDAR"

In DOS ar veni ceva de genu:

In reply to this post by Mihai C.
Mihai,

Te referi la v.surf.rst (nu exista r.surf.rst)? Daca vrei, pot sa iti
rulez eu citeva exemple. Chiar acum nu am decit date de precipitatie
care le-as putea folosi. Daca ai un anumit set de date care vrei sa-l
incerci mi-l poti trimite si rulez o interpolare. Astept o carte ce
iasa vara asta de sub tipar, dedicata analizei spatiale cu R si GRASS.
Prin R se poate face Kriging in GRASS. Sper sa pun un articol.

Mihai,

Te referi la v.surf.rst (nu exista r.surf.rst)? Daca vrei, pot sa iti
rulez eu citeva exemple. Chiar acum nu am decit date de precipitatie
care le-as putea folosi. Daca ai un anumit set de date care vrei sa-l
incerci mi-l poti trimite si rulez o interpolare. Astept o carte ce
iasa vara asta de sub tipar, dedicata analizei spatiale cu R si GRASS.
Prin R se poate face Kriging in GRASS. Sper sa pun un articol.

In reply to this post by Florin Iosub
Salut Marius,

vad ca exista si un v, dar si un r.surf (cel putin asa vad aici: http://grass.gdf-hannover.de/wiki/WinGRASS_Current_Status ).
Inca nu stiu care este diferenta, pentru ca inca nu am rulat nici unul din ele, si nu vreau sa te contrazic, eu doar am citit niste articole pe care mi le-a aratat Florin Iosub si tare mi-a crescut inima :)

Referitor la intrebarea ta daca am date, iti pot furniza un "sample" a ceea ce doresc sa fac, insa daca vrei da-mi o adresa de email, te rog, pentru detalii.

Mihai

                Mihai,

Te referi la v.surf.rst (nu exista r.surf.rst)? Daca vrei, pot sa iti
rulez eu citeva exemple. Chiar acum nu am decit date de precipitatie
care le-as putea folosi. Daca ai un anumit set de date care vrei sa-l
incerci mi-l poti trimite si rulez o interpolare. Astept o carte ce
iasa vara asta de sub tipar, dedicata analizei spatiale cu R si GRASS.
Prin R se poate face Kriging in GRASS. Sper sa pun un articol.

Re: Re: Manipularea seturilor de date LIDAR

Mihai C.
In reply to this post by Florin Iosub
Salutare (din nou),
am mai gasit niste tool-uri pe net, daca comenzile Linux, WinCMD sau DOS nu te multumesc.
Sincer sa fiu, nu le-am testat dar vad din prezentari ca fac ce doresti tu (unirea a mai multor fisiere txt ascii).

Unul este Join (Merge) tool software (7.0) - aplicatie comerciala dar se poate incerca "for free"
http://www.newfreedownloads.com/Windows-Utilities/Text-Editors/Join-(Merge)-Text-Files-Software.html
iar celalalt WinMerge (are functionalitati extinse pentru compararea fisierelor, highlight pt. cuvinte cheie, etc.):
http://winmerge.org/downloads/index.php

Succes!

Mihai

                Salutare,

Foarte util articolul de pe site. Mentionez ca lucrez si eu cu date
LIDAR de o perioada de timp. Sunt foarte exacte si foarte
"obositoare" pt un desktop mediu :D.
in fine...as dori sa va intreb : cum pot uni mai  multe fisiere ascii
(de tip xyz) intr-unul singur sau cel mult 2-3. Am foarte multe
fisiere ascii (peste 1000) si imi vine greu sa le procesez pe toate.

O zi buna!

Cu respect,
geogr. Adrian Covasnianu
