Having just installed an alternative plotter & charts
, while googling for free S57 charts
for S. America I came across your site with interesting Open Plotter !
As the other plotter said I could use a Chart folder structure of my choice I constructed the following
C:\CHARTS\ATLANTIC\CARIB\WINDWARD-ISLANDS\here all chart types
\BRAZIL\ here all chart types
I would rather not have to alter my chart structure for each plotter evaluated, so looked in your user manual for the spec on your chart locations. In the URI Installing Charts | Official OpenCPN Homepage
, I read "Download some charts (see below) and organize them in a fashion that suits you.
" - which implies all I need to tell your program is the root folder of the Charts, and it will search all subfolders when building its library indexes - is that correct ?
My worry is that in the examples you give below, and also in the Toolbox Menu tabs, you seem to have adopted a chart structure predicated by the numerous proprietary/variants and open filetype formats, eg opt/navigation/CM/CM93.
I would have thought from a navigators perspective, the ideal UI would normally 'hide' technical details of chart vendor/version no. and allow users to organise their chart collections primarily by geographic region ? (perhaps separating vendor chart formats as a lower level subfolder within each lowest region, as an aide memoir to what qualities are available for cruising region)
By hardcoding 'Vector Charts' from 'Charts' you would appear to give filetype (i.e. machine over user) precedence over easy UI. Is there any good reason for this ?
I would have thought it easy for the program to automatically take account of 'User Preferences' (show counters/depths less than a certain depth
, pipelines etc) depending on the active/loaded chart type/attributes, to avoid Users having to define Vector types seperately from other charts.
Read some interesting forum posts eg. sailpop about Lat/Long format issues. 10 years back I used the proprietary SeaPro2000, and its DOS predecessor (liked their LiveChart display), which as I remember, allowed the User to specify whether they wanted DD.MM.MMM or DMS format, and how many digits of precision. My preference is for DMS as it matches the co-ordinates on Admiralty and many other H.O. Charts. Might you consider including the option of DMS format in next version ?
I read your Garmin
interface is not yet fully functional. As I use the Garmin
60c, I hope you will have it finished soon !
I read you intend to release a stable v2.3 in next week or so, with many improvements, so I will wait until then to try out.
I wish your Open Plotter/Navigator every success in offering a superior experience to the commercial
