Folium-Karten: die Blockade war eine falsche Alternative
Der einzige Punkt, der in diesem Projekt je als "blockiert" gefuehrt wurde,
ist erledigt. Die Begruendung lautete: Die VRP-Instanz sei ein synthetisches
100 x 100-km-Raster ohne Geokoordinaten, eine echte Karte verlange also
ENTWEDER eine neue Instanz (und damit zwei Dutzend neue abgedruckte Zahlen)
ODER eine willkuerliche Verankerung.
Es gibt einen dritten Weg, und er ist exakt. Eine azimutal-aequidistante
Projektion um den Schwerpunkt des Rasters bildet die 17 Punkte so auf Laenge
und Breite ab, dass die Grosskreisdistanzen mit den Rasterdistanzen
uebereinstimmen:
festes cos(Breite) Median 0,360 % Maximum 2,003 %
cos der eigenen Breite Median 0,351 % Maximum 0,908 %
azimutal-aequidistant Median 0,000 % Maximum 0,001 %
Ein Meter auf hundert Kilometer. Kein abgedruckter Wert aendert sich, die
Gesamtstrecke bleibt bei 619 km, das SVG ist byte-identisch geblieben.
Zwei Befunde stuetzten die Entscheidung: "100 x 100 km Raster" steht nur in
zwei Codekommentaren, nirgends im Fliesstext; und der didaktische Punkt der
Bildunterschrift - die sich kreuzenden Touren, die KEIN Fehler sind - wird auf
einer Karte deutlicher.
erzeuge_vrp_touren.py schreibt jetzt SVG UND Karte aus einem Lauf. Ein zweites
Skript haette erneut geloest, und die Routing-Bibliothek arbeitet heuristisch.
pruefe_projektion() bricht ab, wenn die Verzerrung 0,01 % ueberschreitet - die
Zahl im Buch wird bei jedem Lauf bewiesen.
Neu im Build: die Marke {karte:name}, aufgeloest zu einem <iframe> (Leaflets
Stylesheet soll nicht in die Buchseite greifen), im PDF zum Verweissatz - wie
bei {plotly:}. --check bewacht jetzt beide Markenarten auf Existenz der Datei;
gegengeprueft mit einer absichtlich falschen Marke.
Zwei Vorkehrungen, die ohne Messung nicht aufgefallen waeren:
* Folium vergibt jedem Element eine uuid4 - jeder Lauf erzeugte eine andere
Datei. normalisiere() ersetzt sie durch fortlaufende Nummern; zwei Laeufe
liefern jetzt dieselbe Pruefsumme.
* Folium bindet ZEHN CDN-Ressourcen ein (jQuery, Bootstrap, Glyphicons,
FontAwesome, awesome-markers ...). Gebraucht werden ZWEI. leaflet.js und
leaflet.css liegen jetzt in web_04/assets/, die uebrigen acht entfallen.
Nachgeprueft: Die Karte benutzt ausschliesslich L.*-Aufrufe. Ohne Netz
fehlen nur die Kacheln, Marker und Touren bleiben sichtbar.
Gegenrechnung an vier Strecken: Depot -> K1 misst auf der Karte 27,20 km, die
Distanzmatrix sagt 27 - die Differenz stammt aus deren int(), nicht aus der
Geographie.
Veroeffentlicht: 8 Dateien uebertragen, alle dreizehn HTTP-Proben richtig, die
Karte auf dem Server unter 200 erreichbar.
