Right now we don’t we a simple ruler tool in the app. But what you can do is drop a waypoint by touching the Flag button and select either “Drop a Waypoint” or “Drop a Waypoint near Me”.  Then when done, select “Save & Guide” and when you do, the bottom panel will display the heading and distance.You can also, select “Create Route” and then lightly press your finger on the screen to create your waypoints and the distance between the two will show up on the bottom panel.

 

We get asked this question quite a bit and its a tough question to answer by “area” because the size of the area you can download at any one time is determined by the zoom level of the charts. The more detail, the more information, the more storage it takes, therefore the less area you can manageably download and any given time.

Bottom line though, is you can now download an immense amount of chart data at one time (100,000 tiles) and you can download as many areas as you like.

Our recommendation is to download a large, medium level zoom of the entire region of the area you’re boating, and then download as many high-detail regions (typically close to shore, or inlets) as you need / like. You can mix and match as much you like as again, there are not any limitations to how often or how many regions you download (save the storage space on your iPad) – just how much you can download at any one time.
One other idea is to create a Route, and then going back to that Route (once its saved) and select “Download Maps for the Track”. Yes, we know, the language doesn’t make too much sense, but what this does is download all of the charts for your specific route at a fairly close zoom level. This is super easy to do once you get the initial hang of it.
We hope this helps…

cvwr.jpgView any chart in seconds with the new EarthNC Online Chart Viewer!
Combining the power of Google Maps, EarthNC data, and NOAA Raster and Vector charts, the EarthNC chart viewer provides ready access to important boating information. You can view charts in a ‘seamless’ mode or select a specific NOAA chart number for a given area.

When using a supported browser (Firefox 3.5, Safari, Chrome), the EarthNC Chart Viewer will request permission to estimate your location to initialize the map view. Changing locations is a simple matter of panning the map or using the built-in map search tool to jump to a different city or zipcode. Map search can also be used to find nearby businesses, restaurants, hotels, or other features.

Try the EarthNC Chart Viewer

Bookmark and share your favorite spots by creating custom ‘Map Links’ or choose the ‘Embed Map’ option to get code to paste the Chart Viewer into your own website or blog.

More than just charts, the EarthNC Chart Viewer includes ‘Nearby’ and ‘Routing’ tools. The Nearby menu will show NOAA Weather Buoy, FAA Airport Weather, Marine Forecasts, and 3 day Tide Predictions near any map location. The Routing tool lets you draw a custom route on top of the map and save it to GPX, Google Earth KML, or PDF format for later use.

We’ll be releasing new features for the chart viewer in the future including a dedicated Mobile version for iPhone, Android, Blackberry, Palm, and other operating systems.

clampedToSeaFloor_1.jpgThe new Google Ocean capability in Google Earth 5.0 now provides the ability to ‘clamp’ overlays and features to the sea floor for 3D effect.  To start testing this capability, we’ve rendered one of our Hawaii NOAA raster charts in the new format as shown in the image at left.

You can try it out yourself by opening our Island of Hawaii Chart in Google Earth 5.0.  If you need to upgrade or download Google Earth, you can get it at http://earth.google.com

To see the 3D ocean floor, you have to zoom ‘below’ the water’s surface or even better, turn of the ‘Water Surface’ in the view menu.  We’re currently working to update our EarthNC Raster DVD‘s to allow the ‘Clamped to Sea Floor’ option.

sarasotapra.jpgAs more boaters take EarthNC out on their boats, we’ve noted an increasing interest in ‘live tracking’ of recreational boating trips for friends and family. EarthNC has been building a simple system to support real-time tracking based on Google Earth and various low-cost and free components. Read on to learn more about our Google Earth tracking project and be sure to check out our recent featured trips – Captain Bill’s Michigan to Florida Cruise and EarthNC’s Sarasota Poker Run. For a more technical discussion of the EarthNC tracker, read our Sarasota Poker Run Tracking Case Study.

EarthNC Track Server Features
The goals for our tracking system are simple –

  • Support multiple operating systems and GPS software options for Google Earth
  • Have a webcam option
  • Generate Google Earth and Google Maps compatible Map Output for sharing

End User Hardware and Software Requirements

  • Mobile computer that can run Google Earth
  • USB GPS
  • Google Earth
  • GPS to Google Earth software which supports active ‘following’ of the user position in Google Earth such as GooPs Pro for PC, Google Earth Plus, or gps2geX for Mac
  • Air Card or other suitable wireless internet connection
  • USB Webcam if photo capability is desired

Putting It All Together in Practice
From the end-user perspective, if you’re already using Google Earth with live GPS and have a cell air card – sharing your position via EarthNC is as simple as opening an EarthNC Tracking network link in Google Earth coded to a unique user ID. This link transmits the Google Earth view center to the EarthNC server whenever the link refreshes – usually every 30-60 seconds. With your Tracking network link, you also receive unique links to share with friends and family that display your most recent position in Google Earth and Google Maps. These can easily be embedded into a blog or website using our TakItWithMe Embedded Map generators for Google Maps and the Google Earth API.

To share webcam photos while tracking, EarthNC can set up an individual FTP account for photo upload. Most webcam software, including free utilities such as YAWCAM, supports periodic image uploads to the web via FTP. As images are uploaded, the EarthNC server will determine the most recent image and add it to your tracking maps. In the future we plan to also offer a historical track option which will include all uploaded photos.

Contact Us if you’re interested in beta-testing our tracking solutions.

embedtool.jpgLive from the Google I/O Developers Conference!
EarthNC is excited to announce our TakItWithMe Embedded Google Earth map creation tool. Our new tool allows anyone with a website or blog to quickly create their own embedded maps using the new Google Earth Browser Plugin announced this morning. While currently limited to Windows support, a Mac/Linux version is in the works. For an example an embedded map, we’ve added one to our recent Florida Boating Ramps Map page.

Create Your Own Custom Map in a Simple Steps

Browse to the TakItWithMe.com Google Earth Embedded Map Tool

  1. Paste in a Google Earth KML link or Google Maps MyMap link if you’d like to include an overlay
  2. Click on the ‘Load Preview’ button. If you did not provide a KML link, you will get a warning before you continue
  3. Use the Map Navigation Controls or your mouse to set the Google Earth viewpoint you’d like to be the default for your map
  4. Click on the ‘Set Center and Zoom’ Button
  5. Click on the ‘Generate Embed Code’
  6. Copy the resulting code and paste it into your webpage or blog where’d you’d like the map to appear
  7. To create another map, simply refresh the page and start again

Caveats

Given the short lifetime of the Google Earth Plugin (announced at 9am PDT this morning) and the TakItWithMe Beta (completed roughly 4 hours later), there are a few features that remain to be built.

  • The Google Earth plugin is currently only supported on Windows in IE and FireFox. Google has stated they are working on the Mac/Linux versions
  • The TakItWithMe embedded map is set to a roughly 500 pixel by 500 pixel size which is compatible with most blog formats. We will be adding an ability to customize the size of the map in the future.

Welcome to the EarthNC Trip and Route Tool User Guide

The Trip and Route Tool (TRT) lets you create trip and route plans in Google Earth and easily export them to GPX file format for use with stand-alone GPS devices. In the case of Garmin USB GPS units, you can send your trips and routes directly to the GPS using the EarthNC TRT through use of the Garmin Communicator API.

While the EarthNC TRT is designed for use with EarthNC Plus, EarthNC Raster, and EarthNC Online marine charts, the Trip and Route Tool can be used for any type of Google Earth planning.
