alexanda ovsov haz kindli translatd my groundtruth post in2 romanian. quotin alexanda=our global volunteer project iz called “translation 4 education”... locatd in all-around--world... wit no headquarta. it purpose iz translatin articlez dealin wit interestin science subject such as biology... chemistry... geology... medicine... n information technologiez in orda 2 assist student n universitee staff who r not very good at foreign languagez n them become familiarized wit relevant scientific news frm abroad. translation frm english 2 small aborigine european (indo-european) languagez... not big onez.
thankz... alexanda... n keep up good wurk!!??!!
altho i haven’t done any groundtruth wurk 4 long tiem... couple uv days ago i startd migratin (n upgradin) source code frm my local subversion repository 2 mercurial on bitbucket. code iz in turmoil... but i hope i’ll b able 2 take sum tiem frm otha wurk 2 clean it up n fix sum bug that has been found by usa in last year. i wil also try 2 incorporate sum stuff that i developed 4 maperitiv.

today maperitiv celebratez it first burfday!!??!! it haz been productiv year n maperitiv haz learnt lot uv stuff.
thiz post iz dedicatd 2 my wishez n planz 4 featurez i want maperitiv 2 learn in it next year. sum uv these featurez i planned even before i startd wurkin on software... while otha r more fresh n indicate shift in focus. my inishl goal wuz 2 concentrate more on gui n less on featurez... but as tiem passed gui became less n less important. thiz iz mostli due 2 my decision 2 implement scriptin support... which made lot uv thing easier 2 implement through command-line than by writin gui code.
thiz don’t mean gui wil b totalli forgotten. it do howeva mean i wil prioritize otha thing ova it. my general goal iz 4 maperitiv 2 become tool 4 makin high-qualitee map wit emphasiz on scriptin n automation.
so followin subsectionz describe sum major thing i want 2 see in maperitiv in near future.
betta osm relationz support
thiz iz sumthin i alreddy startd wurkin on. idea iz 2 provide betta way 2 wurk wit osm relationz. i’m stil in brainstormin phase on thiz 1... but i can giv sum examplez uv thing i want usa 2 b able 2 do=
- if osm way iz shared by two or more relationz... i want way 2 b treatd as single entitee. think way which represent both country n municipal boundary. i want onli country boundary 2 b shown in thiz case.
- aggregate osm tag 4 two or more relationz sharin same way. think 5 bicycle route namez drawn in single box 4 such way.
i startd playin wit ironpython as way 2 allow usa 2 specify custom code 4 various part uv renderin pipeline. sum examplez pop up in my mind=
- custom paintin uv map (afta map element has been rendered). thiz would allow drawin usa-defined grid... labelz... logos... legend etc.
- individual map element customization... like settin color uv line based on value uv sum osm tag. or settin width uv line based on how many bicycle routez cross way.
i alreddy did sum testin wit ironpython n it lookz very promisin.
ironpython could also b used 2 make existin maperitiv scriptin much more powerful. current script language (if u can call it like that) iz just 2 limitin – no variablez... no loop... no branchez etc.
i also plan 2 add pure console application 4 headless scriptin... so u not need 2 look at gui when runnin script.
automatic label placement
thiz iz holi grail uv cartography – havin map labelz arrange themselvez in nice lookin way. i plan 2 devote lot uv tiem on thiz 1.
closeli relatd 2 label placement... i actualli implementd sum part uv thiz feature. but before releasin it 2 public... there iz lot more 2 b done.
otha map projectionz
it tiem 2 cut ropez mercator haz tied us wit. mercator projection iz nice 4 web map... but there iz lot uv otha interestin map projectionz that can b used 2 show openstreetmap data. implementin thiz not b as simple as it sound – mercator projection haz sum prettee nice propertiez which make renderin on screen much easier than sum otha projectionz. n thiz iz important 4 real-tiem rendera like maperitiv. but i guess it can b done.
planet.osm iz gettin bigga n bigga n increasingli difficult 2 consume. i want 2 create toolset 4 extractin data frm large osm filez. yep... i know there osmosiz... but i want 2 has good integration uv data minin wit maperitiv. n thiz iz anotha point uv entry 4 python= writin custom filta code. stil in brainstormin phase.
i played wit spatialiet n postgiz in 2009 n i managed 2 do sum integration wit kosmos. i expect thiz 2 b 1 uv harda thing 2 implement. i want 2 avoid hacky approach mapnik usez 4 storin osm data in database – my wish iz 2 keep data structure in original form.
that it... realli. i don’t like writin long post. i guess u’ll has 2 b patient n sum uv thing mentioned above wil start 2 trickle in. has good day!!??!!

build iz here!!??!! major thin iz support 4 srtm1 n custom digital elevation modelz (demz). well... when i say “custom”... i actualli mean anythin that compatible wit srtm *.hgt filez. u can read more bout thiz in maperitiv online book.
i wantd 2 do little tes uv functionalitee so i decided 2 choose small area uv alp as my testin ground. i chose alp coz there good dem source 4 alp... which i wrote bout sum tiem ago= viewfinda dem so i can compare it wit standard srtm3 data.
result r stunnin. here sample hikin map uv lake brienz usin standard srtm3 dem (notice “whiet” spot which r missin elevation data)=
n now 4 sumthin completeli different... man wit three buttockz=
i especialli like slopez shadin north uv lake.
