Hvordan bruke kart fra dybdekart.no på en mobil enhet?

For alle Prosjektsjøene til www.dybdekart.no lages det kart i flere formater. Hvilke formater kan variere litt, men disse går igjen på alle:

- PNG er kart for print og visning på skjerm. Dette er et kart i bildeformat som kan redigeres i programmer som Paint eller Adobe Photoshop hvis man ønsker å legge til effekter, ekstra farge etc. Eller så kan man selvfølgelig printe det ut som det er, eller se på kartet på en PC eller liknende.
- ZIP er kartfiler for bruk i kartplotter i båt. Husk å sjekke beskrivelsen for å se hvilken kartplotter de passer til. Filen må lastes ned på et minnekort, unzippes (pakkes ut) og så kan man slette den originale filen man lastet ned og putte minnekortet i kartplotteren. For tiden er det kart til Lowrance/ Simrad og Humminbird som ligger ute, men Garmin vil også bli tilgjengelig.
- KMZ er for kartprogrammer som Google Earth eller tilsvarende programmer. Google Earth kan lastes ned gratis til PC, Mac og diverse mobile enheter som nettbrett og smarttelefoner. 

Her skal vi se på KMZ-kartet for Vansjø på en IPad Mini. Vi begynner med å gå inn på Vansjøkartet, og trykker på KMZ-kartet.



IPaden hopper da til et bilde hvor den spør hvilket program den skal åpne filen i, her bruker vi Google Earth som du kan laste ned gratis fra AppStore:



Da åpner Google Earth appen seg automatisk og tenker litt mens den begynner å laste inn kartet:



Etterhvert som kartet lastes inn (kan ta tid hvis du har dårlig dekning) vil GE-appen automatisk zoome inn på området kartet dekker:



Derifra kan man zoome inn med fingrene til det området man vil se på, i dette tilfellet Elverhøy der Mosseelva begynner:



Slik ser området ut i GE uten kartet:


Du kan også bruke IPadens innebygde GPS så lenge du har en variant med SIM-kort i. (Den litt rimeligere IPaden som bare har WIFI har ikke egen GPS.) Da vil din posisjon vises som en blå prikk i kartet.

For store vann eller hvis man har dårlig dekning, kan det være lurt å bruke varianten av kart som er uten isobater. Isobater er enkelt sagt fargene mellom dybdekonturene i kartet, og med kart som ikke har disse blir mengden data som skal lastes ned over mobilnettet mye mindre. Ulempen er at man mister litt av den gode oversikten man får i kartene med isobater.

Varianten uten isobater ser slik ut på dybdekart.no


Her ser vi på kartet for Tyrifjorden, uten isobater:


Zoomet litt lengre inn:


Du kan selvfølgelig bruke varianten uten isobater med GPS-funksjonen også, så du ser din posisjon i kartet.

Kjekt å ha for vinterens isfiske!

What is the difference between Lowrance HDS and Lowrance Elite HDI

Ever since the Elite 7 HDI came on the market I have recived a lot of questions regarding the difference between the HDS-range and Elite HDI. In this article I will try to list most of the differences, seen from a keen anglers point of view. This also means looking at most of what Lowrance has to offer, but I'm sticking to models sold today and models I personally would recommend. The three main model-series, plus the newcomer Elite CHIRP. HDS Gen 2 , true multi function displays (MFD) with button-operation and screensize from 5" to 10,4". HDS Gen 2 Touch , true multi function displays (MFD) with touchscreens and screensize from 7" to 12". Elite HDI , "stand alone", ie not ment for networking besides VHF and AIS. Button-operation and screensize from 4,3" to 7". Elite CHIRP , as Elite HDI but with CHIRP-sonar and faster processor in adition. Screensize 5" and 7".   HDS Gen 2 Units from this series are seen while fishing

What is the difference between HDS Carbon and HDS Live?

Here we go again, a new generation of the Lowrance HDS. And with that Facebook and the different forums are flooded with questions referring to the difference between the new and the old. So what is the difference between Lowrance HDS Live and HDS Carbon?

What is the difference between HDS Gen 3 and HDS Carbon?

Whenever a completely new model or a rewamp of an existing model comes out, we get the same question: "What is the difference?" Lowrance HDS Carbon Previously I have written a few articles about the differences between some of the (now historic) Lowrance-models: What is the difference between Lowrance HDS and Lowrance Elite HDI? What is the difference between Lowrance HDS Gen 2 and HDS Gen 3? This time we will take a look at the difference between Lowrance HDS Gen 3 and the brand new Lowrance HDS Carbon that was released 15. december 2016. We will look at the technical stuff, and try to translate that into what it will mean when out on the water. Lowrance HDS Gen 3 HDS Carbon is actually the fifth version of the popular HDS-series. Before it came HDS Gen 1, HDS Gen 2, HDS Gen 2 Touch and HDS Gen 3. HDS Gen 2 Touch marked a new area of how Lowrance run their model-updates, since it was released shortly after HDS Gen 2 and the two lived alon

What is the difference between Lowrance HDS Gen 2 and HDS Gen 3?

The cyclus in which models change have become shorter and shorter. Is there any real difference between them anymore? When I started out in this game most people would say that their sonar should stay onboard for 8-10 years before they would even consider upgrading it. Everything with less then 5 years on it was considered "new". But as with all things containing a circuit-board, development has been ever accelerating and we are now down to a two or three year cycle between model-changes. I belive that this is to the consumers advantage, but is "the new" always better then "the old"? In most cases the answer to that question is "yes", but it`s up to you to decide if that difference is big enough for you to spend your hard earned cash. Technically it is easy to spot the differences, but whether you will notice it out on the water is a more subjective mather. In this article I will try to look behind the marketing, and point to the actual diff

What is the difference between Lowrance HDS Live and Elite Ti2?

Lowrance as a brand of marine electronis is well known to all anglers, but the differences within their range of different models seem to cause quite a few questions out there. Here we will try to outline the difference between Lowrance HDS Live (top end) and Lowrance Elite Ti2 (middle range). Lowrance Elite Ti2 vs Lowrance HDS Live (photo; lowrance.com) As usual, we will start with the tech and then try to translate those technical aspects to practical differences while out on the water. Hardware - housing, screen and connections. The screen and housing on Elite Ti2 is the same as on the previous Elite Ti, and again more or less the same as on HDS Gen 2 Touch. (The memorycard-door and mounting-bracket is different from HDS Gen 2 Touch.) This is by no means new stuff, and compared to the more advanced housing and screen on HDS Live, Elite Ti2 is starting to show its relative age. However, with that in mind it is worth noting that when looking at the competition, several of
